I am building a replica of the Union Pacific Big Boy 4014, the largest steam locomotive ever built, and I am building it on the Just Minecraft server. All of the cars I am building exist and are still in service as part of the Union Pacific Heritage Fleet. My builds are exterior only, so no interiors. (sorry)

If you are interested to learn about Big Boy 4014 or the UP Heritage Fleet, look at these two links:
