CNR 3737 :: starting on the cab

On Friday, I spent another pleasant afternoon with Andy Malette in his workshop, as we worked on our CNR 2-8-2 projects. Our main task was to start work on the cab.

When the CNR acquired its USRA Mikados from its US subsidiaries (Grand Trunk in New England and Grand Trunk Western in Michigan), it retrofitted many (or all?) of them to accommodate cab curtains to help crews cope with Canadian winters. This required re-shaping the back of the cab roof, above the footplate, to square it off and allow the curtains to hang properly. It also required adding a back wall to the cab, over the tender.

There were several variations on how they did this. One such is shown in the photo of 3715, below – found in CN Lines Volume 6 Number 4. I had this issue on my CN Lines DVD – which I highly recommend.

CNR 3737 - cab

As the image suggests, CNR simply scabbed in some metal to square off the bottom edge of the cab roof. On 3737, the added piece drops down slightly after the walkway, but not every locomotive had that feature. Based on prototype photos, the 2-8-2 I’m modelling – CNR 3737 – did not: Its cab roof went straight across, or ever so slightly upwards, with a very small rounded corner at the rear. The rear cab wall was also inset slightly – not flush as shown in the photo of 3715. My prototype did, however, have the two small vents in the cab back and the smoke deflector on the roof.

As the photo above shows, I’ve soldered in angled pieces of brass – then cleaned up the excess solder and filed, sanded and polished them to shape. I’ve also cut a piece of 0.020″ brass for the back wall of the cab, and started laying out the location of the vents.

Other progress of note:

I’ve stripped the boiler and smokebox front of many of the appliances that are either not needed, need to be relocated, need to be out of the way to work on things, or need to be replaced with CNR-appropriate versions. There are a few holes to fill. I also need to rework the walkways, which have a step-up to clear the air compressor and water pump on this side of the locomotive.

Finally, thanks to our friend Simon Parent, Andy and I have lovely CNR-style spoked wheels for the pilot truck:

These are the same wheels that Simon used on his CNR 2-10-2s. He sent us some (along with castings for the Elesco feed water heater), and Andy mounted them on axles for us. They sure complete the CNR-ization of the pilot.

I’m pleased with the progress!
