Nation Wide Lines postedAs Steve indicated, there are 2 different styles of these handrails. Additionally, some engines come without the handrails installed. I know the 1270 does not have them and I also have an odd engine that did not have them installed originally. Generally, the ones that did not have them originally, have the mounting holes covered in paint (ie the paint fills the opening and dried that way).
As for any reproduction parts, no I am not aware of anyone making these. You would have to find a junker with the parts you need in order to get some.
Here are a couple of the odd ones that came without handrails.

Mine has flat handrails on one side- slots on the other-and this odd light that I guess someone added. Also the circles on the ends that look like electrical box punch outs. I think it was repainted too, because there is no residual lettering at all.
Did any of these come with lights? Was there ever anything in that unused hole in the roof?
