Modeling these?

I guess I took too long to post... :P

No, those have even a different end handrail.  The fireman side hand rail is also slightly different where the rail curves up to the cab.

The plan is for these:





Also 403.

I haven't decided if I want to do the two different as delivered yellow schemes or the later orange and cream scheme.  I like the yellow better, but the orange fit's onto my 1968 era.  There was a time in the early 60‘s you could mix them together.

One side note, #49 of the St.J&LC that Chris posted was sold to the city of Colorado Springs in 1978 to work the power plant.

That sounds like a good solution. How much width do you add to compensate for over-etching? Another .125mm overall?

.14mm if I remember correctly but I would have to check the artwork.

Thanks!  at those minumum etchign widths this is quite important (or the etched part will simply wenish).  I know that you understood what I wrote, but I think I used incorrect therm. I think that the term is undercutting, not overetching.

I use .125mm stainless and make the handrails .125mm wide.

If my math is right, that's under one scale inch in N -- small enough to make scale-sized pin lifters, and the flat/etched aspect would not be very noticeable (esp. if painted a dark color).

If you are looking to fill out the sheet, might could I send you the artwork to do some handrails for a GP18 (low hood) and C420?
Thanks much,

Even if painted a light color, it's not noticeable.

I think @coosvalley was looking for just such an opportunity?

Looks like I got a bit carried away in the height of them:

LOL - that was my thought exactly. What were you thinking?  But those could be used as chin-up bars by the conductor.  :)
End handrails are usually the same height (or close) as the ones on the sides.

Maybe a tad. But you sure underdid it with the weathering  :D
Nice engine Wolf, what's with the skewed cab?
