Part 2 (cont)
Finished doing the remaining engines.
I was able to use the existing marker lights that came with each engine but it was nice to have the cal scale available as 'back up'. A couple marker lights broke free when drilling and I had to re-solder them back on. Also, from drilling holes in thicker brass, ie head lamps, I went through 3 of the #55 bits so buy them by the 'dozen'.
I drilled a small hole in the fire box front to route the wires.
This cab forward was done the same way as in the previous post.
The tender lights also go drilled out. I noticed some tenders have slots where it appears that marker lights are hung (ie, big boy, DM&IR yellowstone) so I'll have to research and see if the lights were on the back of the tenders.
A caboose got the tomar marker lights. A couple holes were drilled in the bottom plate so wires can be run to the trucks.
I was thinking it would be cool to drill out the number boards but that would, probably, be difficult to do and I've never seen any hollow ones (save O gauge).
