Take a look here:
http://www.lahacal.org/gentleman/index.htmlDon't be put off by the fact that it is the 'gentleman's page. Go to the 'atire' section, then click on 'informal atire'. There are a couple of good photos there. Often times, blue collar men simply wore the cast off clothing of the upper class. It would be a bit rumpled, and probably out of fashion to 19th Century eyes, but to our eyes it would not look very different. Look up the 'sack coat'. Very common with the working class. Vests were common too. Even a 19th Century working class man was considered undressed if he was seen in public with a shirt without a vest. Not neccessarily a fancy vest, maybe something plain and second hand, but most men wore a vest in public. Bowler hats were very common with the working classes too.
One thing I can positively tell you about railroad workers clothing in the 19th Century; don't expect to see the striped overalls and hat that we associate with railroad engineers today. Definitely 20th Century. I've been a train enthusiast all my life. I have lots of photos of train crews from the 19th Century. The striped stuff does not show up until the 1900s. Most RR men wore heavy work clothes. Heavy boots, heavy trousers often with suspenders, simple shirt, either collared or not depending on the date. Most wore a pretty shapeless slouch hat. Newsboy type caps were pretty common too. The conductor often wore a pretty typical suit with jacket, vest, trousers and tie. The foreman of a construction crew would have dressed just slightly better than his crew, perhaps a jacket, perhaps a jacket with vest. In truth, there was nothing particularly specific about RR men's clothing to differentiate them from any other working class men in the 19th Century.
Here is a fabulous photo of a train crew member from about 1900. Notice the hat:

Here is a photo of an engine crew from 1908. It is an eastern railroad, the NYC, but dress would not have been much different in the west:

Here is the crew from a logging engine right around 1890:

Hope this is of some help.
