My local Hobby shop stop selling styrene! Go figure. I am starting my next project
only Number 76 its sister locomotive and have no styrene for the new boiler or the cab. An online source would be much appreciated.
Are you going to make all of those people, too? 
I like the dude hanging on for dear life to the trestle bent.
I usually order directly from Plastruct.
Thanks for the links, I’m checking them out. As for the people, yes, eventually. I tried to make the guy hanging on the tie already. He ended up being the figure Vincent and looking more like a Dutch impressionist of the late 19th century, so I called him vincent instead 
Richard, what year was that photo taken? Looks like a good reference for period clothing, hair, etc. Interesting that almost all of them have their shirts buttoned right up to the collar. All long sleeved shirts too, despite the tropical climate.
Thats a circa 1904 photo, I believe, but I’m only guessing because the rest of the photo shows the tender converted to oil, and that particular engine was converted to oil in 1904, so it could be 1904,05,06,07. I’m not sure when the headlight changed to electrical I’m still researching that, but I have seen an old 1905 photo with the same headlight as in this photo.
Yes, the all wore proper Victorian/Edwardian garb. My Grandfather was a fireman (not on a train but in the fire department) in the early 20s and he wore a full brass button jacket and cap to work and to a fire. I have a pic of my Great Grandfather who was a Capt of the Honolulu Mounted police in 1906 and he also has a full suit jacket with brass buttons and all. And another of my Step Great Gramps who was the Capt of the steam boat Hale Akala in 1911 and he has a full jacket with brass buttons.
I don’t know how those guys did it back then; when I’m back home I can barely keep a shirt on for more than an hour, much less one of those uniform jackets.
