I modeled this locomotive after a saddle tank engine that used to run on a railroad where I used to live. Locomotives like this were popular due to their size and used in industrial areas mostly. The engine I built was based off the locomotives made by the H.K. Porter company in Pittsburgh during the late 1880's. The company was famous for building many light-duty engines most using the saddle tank configuration which stores it's water supply in the U-shaped tank on top of the boiler instead of carrying a separate tender.
The engine here is was originally going to represent standard gauge but half haw through building I realized it looks (to my eye anyway) a bit too long. However this is no big deal, compared to the track I'll just say it's a 3' narrow gauge locomotive ;)
It's a bit flimsy and again a display piece. The cab is made from plates and very few bricks. I also tried to build it like the actual locomotives. I started with a frame and then fit the boiler and firebox into the frame and built from there.
Thanks guys. :) I'm happy I finally got my LEGO unpacked after the move we've had and now able to build trains again. Some of my mocs got damaged in transit such as my class B 4-6-0, but I'm glad this came out alright at least.
