It’s an interesting experience to be reminded you need to update the blog while visiting a friend at a live steam club.
At the tail end of the last blog we were focused on getting the fleet through winterfest, and looking forward to getting 16 into the nice warm VC for the winter. Nothing has since gone to plan. While much has happened in the past few months, one long, winding saga has been dominating work.
2600, a car seemingly cursed, decided to fail on us one winterfest night. A large group had come in, and we intended to run 2600 as a second section behind 4, a bit of Montreal action in the cold. The car powered up, built air, but as soon as the brakes were released, problems began.
For those unfamiliar with Safety Cars, they use multiple brake lines, and critically for us there is an “emergency” pipe that needs to be “charged” to above a certain pressure to allow the brakes to release. If this pressure is dropped, say by the motorman releasing the deadman handle, the brakes will automatically apply to full emergency. Part of the system is something called the “Pilot Cut Off Valve”, which we will shorten to PCV. This valve acts as a relay, taking in input from both the position of the brake handle (pressure in brake cylinder), and the deadmans, and either opening or closing a vent to atmosphere on the Emergency pipe, which we’re also going to shorten to EM pipe. This valve is not operating via pistons and slide valves, rather it’s using rubber diaphragms, including to seal the EM pipe.

The symptomology presented as such. The car would build into an application, behaving normally, but as soon as you attempted to charge up (apply pressure to EM pipe, and release brakes) issues began. The EM pipe would climb to full pressure, but instantly a hissing would be heard from the #2 end of the car, with the EM pipe pressure dropping rapidly, and at best holding at 10 PSI, nowhere near enough to allow the brakes to release. Moving the brake handle back to apply would slow it down, but releasing the deadman’s would entirely silence the hissing. So, clearly the EM pipe isn’t sealing. The sound also gave an indication of where, just behind the motorman's seat. Sure enough, there is a valve hiding back there.
#1 end valve, hidden just behind the seat.
At the time, the purpose of the valve was a bit of a mystery, but thanks to help from both Gord Mquot at Halton county, and Jeff Hackner at Branford, we were able to figure it out. This valve is a hybrid of a PCV, and a door interlock. 2600 has pneumatic doors, including treadle doors that open when someone stands on the treadle. These valves (there’s another one on the #1 end as well) make it so the car cannot release brakes when someone is standing on the treadle. 2600 is of course not a standard safety car, it’s somewhat more complex, and in fact has 3 whole separate PCV’s in it. Two are hooked to the treadle doors, and one seems to be operating as a standard PCV and is located under one of the bench seats. While it may have simply been possible to cut out these door valves as the treadles aren’t in operation, we weren’t really comfortable doing that, just in case we were wrong with what the valves were really doing.

The labelling would later turn out to be inaccurate.
As stated before, these valves are diaphragm based. Upon opening them, the diaphragms were showing major signs of age. Some had become rather hard, some were cracked and distorted, and the actual sealing face of the lowest diaphragm was pitted and scored. Amazingly, Wabtec (successor of Westinghouse air brake) still makes those diaphragms, but in limited quantity. Because of this, there is an immense lead time on getting them made, and shipped (we’re still waiting). Because of this we decided to try something. Advancements in 3d printing has given us the ability to print flexible rubbers, something we’ve already experimented with for some gaskets. The diaphrams in these valves are mostly just round, with some raised features for sealing, and as such were easy to model and print. I’m happy to report that as of writing the printed diaphragms are holding up perfectly.
While working on the PCV’s, we decided to go through some of the other valves, cleaning everything out, renewing seals, and lapping in some of the sealing surfaces. After months of work, 2600 was able to finally go back out into service, at least for a couple weeks.
A few weeks later, the curse strikes again. Some issues with the North Road Switch not playing nice with 2600’s taller flanges resulted on the car derailing and dropping the west end truck on the ground. The good news, the car climbed itself back onto the rails fairly easily, the bad news, the car tried to take a new shape.
Oops
The bend in the Side Sill.
Anyone who has worked on any vehicle in the broadly north half of the continent is well familiar with the unimaginable power of rust. Between rust jacking bending and tearing steel like paper, nuts and bolts becoming effectively welded together, or corrosion simply making masses of steel simply vanish. Most lightweight cars are prone to rust, almost always in the same spots, right above the bolsters. The steel framing there often becomes more enclosed, trapping dirt, water, and sometimes even road salt. There is also quite a lot of wood in the frames of these cars, making up most of the floor, which also holds moisture against the steel framing. 2600 is very much a victim of “lightweight disease”. Hidden behind the skin of the car, the steel framing had mostly rusted away, and no longer was connected to the side sill.
The side cut open, and rotted structural steel removed. Sitting below the car is the skin, with some of the rotted structural steel still attatched.
When the car came to a stop, it rocked hard to the side. The rocking pushed up on the bolster, bending it and the side sill upwards. With no framing above it, it was free to bend. While this didn’t stop the car from running, it isn’t safe to leave. Also, not exactly a good look.
So the car was taken to the shop, and work began. First, cut away the outer skin of the car and assess the rust, see what we need. Layers of horse hair insulation had to be removed, as did mountains of rust and scale. Bending back the side sill was going to be a challenge. The amount of wood in the car meant using heat should be avoided as much as possible. Going at it with sledge hammers wasn’t having any effect, and trying to put a jack between the sill and the still intact upper framing only served to try and twist the framing out further. The solution as it turns out is a hilariously Rube-Goldberg mess. A chain through the sill, a 6x6 wooden block, an upside down rail, and a 40 ton hydraulic jack.

A good example of the corrosion, this piece should be at least 2 inches longer.
With the sill pulled straight, new steel had to be welded in to restore the structure. Much of the original skin of the car was able to be welded back in. Because everything had to be welded, and getting the skin off required grinding the rivets away, false rivets had to be made. The fake rivets were made with a form tool on the late, and then plug welded into the original rivet holes. A thin strip of new steel did have to be welded in to patch where the skin had bucked and rusted through.

Bondo and Primer
Awaiting application of the stripe
The welds were ground down, buried under bondo, sanded, bondoed again, primed, bondoed again, re primed, ok still needs more bondo, try priming one last time, eh that’ll be fine, and the given a new coat of Montreal Tramways cream. The red stripe was re applied, and the repair was invisible.
Sadly, this bend in the sill was not the only damage to the car. The westmost gearcase was torn open when it hit a track bolt. This, fortunately, is not actually that hard to repair. The car was nosed over the pit, the cover removed, cleaned, and patched. Whereas the sill repair took 2 weeks, the gearcase took 2 days.

Back together.
2600 finally went out to be test run post repair, for a bearing to overheat. This bearing was found to have a lot of water intrusion, so it was cleaned out and the waste replaced. The car was placed back in service, and overheated another bearing. This also had water intrusion and had to be repacked. As of writing, the car is back in service, but the summer is young, and I’m sure there will be plenty more of the ongoing curse of 2600 in the next update.
Winding back the clock, to just after the close of winterfest, we had planned to bring 16 into the VC, and give it some needed attention in a heated building. Scheduling moves took longer than anticipated, on top of also having other work take priority (more on this in a future post). By the time we were ready to move, the snow came. Instead of moving 16, we found ourselves buried under 2 feet of snow. We currently don’t have a functioning plow, and even if we did that wouldn’t get everything cleared out enough to get 16 into the VC.
That lack of plow, though, it got us to thinking. Last year Capital Transit sweeper 010 went into the VC to be put on display, and while it hasn’t in many years, it is ostensibly capable of running. So, why not take the season to look over the car, see what it’ll need.

This is the sagged west end.
So, first question, can the car sweep? No. The brush motor is no longer in the car, in fact it’s under open car 355 as a traction motor. Assuming we’ll be able to find it a motor in the future, what else is left of the brushes? The car was stacked full of parts, the brooms, carriers, drive chain and sprockets, but something else is missing. The actual axles for the brushes to ride on. Asking where it was, or what had happened to it, gifted us the greatest two word horror story;
“It shattered”
It’s a 10 foot long 2 3/8th inch thick solid steel shaft.
More things came to light as the car was cleaned out, we only have enough parts for one of the ends to have its brushes put together, as it turns out that’s how the car came to us, with one end missing its brushes. Obviously at this point, getting the car back into service quickly is not in the cards, but that’s ok, we can still do cosmetic work, assemble the one set of brushes, clean it out, get it lit and looking good for the public,

Brooms laid out on the floor.
Something else quickly became apparent with the car, it’s got some wood issues. The west half of the car has some problems. The most obvious is that it sags severely, and shows many signs of rot and termite damage. Compounding this damage is the issue that most of the steel braces have been mostly, if not entirely, disconnected and have simply been hanging. The brush holders have been hanging from the wooden frame, but with no bracing. Some of the bracing couldn’t be reattached, with their mounting hardware being cut off or damaged. There are solutions, but nothing we could affect in the VC. What could be reattached however was, and instantly that end of the car felt much more solid.
Another problem was also discovered. The floor on the west end of the car had begun to feel less like floor and more like trampoline. Turns out, the large castings that hold the brushes are quite heavy, and they had all been stacked on top of a crossmember that was already full of knots and damage from the brush drive chain wearing into it, cracking it in half. The next crossmember was also cracked, partially from the weight, but also from the rod for the brush height adjustment going through it, and removing most of its mass in the middle.
Once all the parts were out, the repair seemed quite easy. Get under there with a jack, some timbering, jack it straight, and through bolt some steel plates over it to gusset it solid.
This went… pretty smoothly. Shocking I know, but we gusseted the first of the two crossmembers, patted ourselves on the back, and went home with plans to do the next one, the more complex one with the height adjust going through it the next morning.
So the next morning, we climb under the car, and discover the formerly straight and level cross member was once again at an angle. The gusset hadn’t failed, instead the piece cracked elsewhere, further along where the brush drive chain had been damaging it. Our repair hadn’t fixed the problem, it simply moved it.
The first attempt at repairing the crossmemeber.
One trip to the hardware store later we once again jacked up the broken cross member, undid the gusset we did the day before, and bolted onto it a brand new 2x6. Steel brackets also were added to help give more support, as the original tenon joints holding in the crossmember were also starting to show signs of cracking (yay). The next crossmember down was also now sistered to a brand new piece of timber, that was also bracketed to the side sills.
Sistered in new lumber. Not going to crack now.
Finally, that particular issue was solved. The rest of the winter inside was spent continuing to clean the car, as well as wire in a second string of lights next to the cars original, so it can be illuminated off of domestic 120vac power. The east end of the car, the end in better shape, had its brushes reinstalled, though only for display purposes. How did we solve the issue of the missing axle? Well as it turns out steel fence post is often manufactured in 2 3/8ths diameter, and in 6 foot segments. Take two pieces, cut a foot off each end, and they’ll slide right in meeting in the middle of the center bearing. Now, this won’t be able to spin, as it’s not a single piece, and not exactly the strongest, but for display purposes, it’s just fine.
Brushes installed for display. One of the cut off fence post ends can be seen under the brush.
Completing the deal, display stands were made up, one to hold a spare broom, complete with bristles, and another to hold up one of the conduit plows, showing off how the car could run on both pole and underground conduit.

While working in the VC, and right next to it, Volunteer Jayden decided to take on relettering the Poneman Mills Locomotive.
Lettering going on.

Now that the weather has warmed up, we have returned to the shop. Some light steel work has been done on 3001, as well as other things (again, future post), but most recently we’ve been back to working on CA&E 303. Work resuming was delayed by 2600, so work has only begun in the past few weeks. The poles have been taken off and the bases rehabbed. One of them was very worn, and has been receiving some new machine work to be brought back to something resembling good condition. Pulling up the running boards has been a challenge, as the oak used to build the standoffs has seized and rusted the screws that were holding them down. We ended up having to cut the running boards, and slip a metal cutting blade on an oscillating saw underneath the standoffs, cutting the screws and freeing them from the roof. As of writing, the running boards and very last of the canvas has been removed and we are finally down to just bare wood.

This very long post has honestly been just a sampling of what’s been going on. There is still much for the rest of this year. We have grants we need to complete to get 303 and 836 painted, and need to get 3001 cosmetically complete and in the VC before opening season of 2027. As I’ve mentioned a few times there will be a separate update on 3001 in the near future, as a lot of things have happened with that project in the past few months.
