Like most sermons nowadays, let's start with a funny story. While the 36 was at Cleveland, the original type J governor either failed or was thought inadequate to the task of running on a 750V rapid transit system, so it was replaced with a newer model. (Rod could tell us what it was, I forget.) Anyhow, in service it flashed over and started burning, and the car filled with smoke. They hit it with a fire extinguisher, but the smoke got worse, so it was pulled out of the subway out onto the bridge until the panic was over. And that was the end of that, until today.
Here's what the area looks like before we start. Fortunately, none of the car's wood was actually burned; only a small amount of paint on the floor was singed. The white stuff is powder from the fire extinguisher, and the black stuff is soot. So let's just vacuum and scrub until it's nice and clean.
The goofy red paint will have to be changed, of course, but otherwise all is well. Al Reinschmidt was out today to help, and together we recoated the interior of the new governor with Glyptal, checked that we had the right piping, and Al installed it as seen here.
The wiring meggers OK, but looks a little tired. We may want to replace the wires with new material, but that isn't affected by having the governor in place.
Then we started inspecting the compressor, and here the news is considerably worse. The commutator is grounded, the fields are grounded, and the brush holders, with the leads disconnected, are grounded. We could not understand how the isolated brush holders could be grounded, but there it is. And the commutator is badly worn. This compressor is probably not worth trying to fix. We looked at the spare compressors along the avenue, and at least one appears to be a better candidate to the naked eye.
Al helped me retest the parts of the control system that have been installed so far, and everything appears to work fine. So that's a relief. I wanted to install another contactor, but it turns out there's not quite enough clearance. The second box, which opens towards the center of the car, is mounted lower than the others, so I'll have to rebuild my little platform. Thus there will be a slight delay.
We went out to check on the 321. Here is the nice new access road to the south yards, which was installed last fall. I guess this is an extension of Railroad Avenue. Anyway, it's nice and solid, and here's the stone culvert over the drainage ditch between 13 and 14.
Finally, Al helped me clean up the interior of the 319 so it can be cleaned for service. The Operating Dept. cleaning days are coming up soon, and this help is greatly appreciated. The 308, 309, and 319 are ready for some TLC.
