Well yesterday and today I finally bit the bullet and tried my hand at weathering a piece of rolling stock.  I'd been putting this off for some time as I was unsure if I was going to be able to achieve the standard I wanted.

My idea is to be able to get one piece done in a hour or two (and down under an hour with practice), I also want a weathered look that is in line with the "good enough principle".

As I'm creeping towards completion of my roundhouse I still have no good idea about the roof. What kind of roof should I use? What's prototypical for an American roundhouse and easy to model in N scale? Here is a picture of the structure in question as it looks today:

Scooped 3 of these off Ebay for cheap. They run well and I would like to replace the stadard LED on them to a better one and add ditch lights. Can it be done? The head light comes on when running forward and the rear ligts only when running backward. Should they be on all the time or leave as is?

LED suggestions?

Ditch lights. Guess I'll have to drill new holes for them, but what can I use for LED's? Has anyone done his before? I"m going to run them on a table layout so DC will be the power supply.

Suggestions?
