typical 1950s American freight train - real world MOCs of five freight car types

[Murdoch17]

Seven small 1950s freight cars of five designs. Each was built to a length of about 16-18 studs per car with two bogies per vehicle. (Originally they had just two fixed axles when originally built, but this was recently fixed to be more prototypical for American freight cars.)

The whole train going into a tunnel.

The freight cars are (Left to Right):
- cattle car
- boxcars (x2)
- flatcar with bulldozer load
- Octan petroleum tankers (x2)
- caboose

This livestock car was heavily inspired by the one in 2014 CITY set 60052 but with a roof for more realism. I can now understand why LEGO left it open top in the set, but I managed to make it work. The roof (which was designed with the same look as the boxcars) is even removable and the ramps fold down so you can take out the cow.

These two identical boxcars were inspired by set 7597 from the 2010 Toy Story 3 line. They were expanded in length and had the roof trapdoor removed.

Here we see a small 1950s-looking bulldozer on a flatcar. The construction equipment was inspired by CITY set 60140, except in yellow with 46 technic links as the caterpillar tracks instead of red with rubber one-piece tracks. Other things such as headlights and gears (for the treads) were added, and the blade was shortened in width by two studs.

These two oil tanker cars came from my own imagination, and are made in Octan livery.

This caboose model is slightly inspired build-wise by the Katy Caboose (as in, "The Caboose who got Loose" from the children's book) model I copied in late 2021 from @zephyr1934's MOC.
