Trying to glue brass numerals to a surface has been not fruitful for me.

I can line them up and with the eye get them perpendicular,

but I need a thin adhesive that doesn't dry fast in order to position the numbers, which takes a few minutes.

I created sets of scale builder plates, each with the right serial numbers and dates for ET&WNC ten-wheelers 9, 11, 12, and 14. I also used photos of the real number plates to make scale versions of them.

Bachmann did a great job on most of the engines but they always do their plates are opposite images of what they should be (black lettering on bronze which of course is opposite of how they looked in real life).

I’ve posted the routing of LED leads in the “Whats On Your Workbench?” as snipits.  This is slightly more involved so I’ll post it separately. 
 

The first step was to solder a lead to the positive side of the small connector board.  Just like the decoder the hot wire goes to all the LEDs.

This CNR wafer was covered in a very tough and durable gloss lacquer.

I managed to rub through the gloss lacquer covering the wafer using an eraser and realized it is not a decal, but a pad printed wafer on the black finish.
