I have three on the go at the moment, NAR examples. I haven't posted any of my progress yet due to the fact that there's not been much progress. When I get some time I've been working on the A-1-A trucks, but it seems that time is becoming a rare commodity these days.
I do have a drawing of each, NAR and CN, they are not the same. Also, I'm not sure about the prime mover in the CN engines, but from what I can gather they had off centre exhaust stacks, whereas the NAR engines are on the centre line.
I have a NAR paint drawing which shows both ends and a side view as well as a top view. The CN drawing only has one side and one end, the short end.
As CN is still operating them, as of last weekend, I'm sure they will have a drawing for you to beg from them.
The Alberta Railway Museum acquired the last example of a NAR unit #302 last year, which I might add they have done a wonderful job painting it. Unfortunately it only has the two axle flexicoil trucks as per CN standard.
If you would like a copy of my drawings send me a private e-mail with your mailing address.
