CNR 3737 :: Piping near the cab

CNR 3737 - Piping.

I’ve been exchanging notes with a reader and he mentioned he’s hoping for more progress reports on my CNR 2-8-2 – so this one’s for you!

Progress has been slow, so there’s not much to report. Our schedules have conflicted more often than not, so my friend Andy Malette and I have only been able to hold a couple of work sessions over the past several months. That’s fine – it’s a hobby, and the work will wait until we’re able to do tackle it.

At our last session – late last year – I installed some piping ahead of, and underneath, the cab. Unfortunately, I’d forgotten to take along some brass castings that were essential to this work, so I had to revisit the piping, cutting into it in some places and re-bending it in others. But the result can be seen in the photo above.

I still have to do the other side.

I have to confess that tracing pipes on photographs makes my head swim. The pipes duck in and out, behind appliances, under running boards, and so on. And the old photos are often a bit grainy or taken at a typical, 3/4 front view from track level. So sometimes, it’s a guess at best. Now, it’s an educated guess: I’m following piping diagrams from various sources, including the Model Railroader Cyclopedia – Volume 1. But those sources are guidelines, at best. As any student of steam locomotives knows, appliances and piping typically varied from unit to unit, based on where and when the locomotive was last shopped and what was on hand at the time.

I find that printing out the photos – or sections of photos – in a larger size helps. I can then use a selection of markers to trace each pipe in a different colour. Assuming, of course, I can see them in the prints…

Locating piping is further complicated by the fact that the pipes cannot always go where the prototype put them. In the photo above, I’ve had to run the lowest pipe parallel to the running board until it clears the space required for the trailing truck, then curl it downwards. On the prototype, this pipe cuts across that open space at more of a 45 degree angle. But of course, I want my model to be able to negotiate the curves on the S Scale Workshop modules (for which I’m building this model) – and my own layout.

Back to staring at photos and taking notes. It’s all part of the learning process.

  1. At first I thought the photo was the real engine, until I saw the solder coil! Great work! Thanks for posting.
    Cheers, Gord
