mine carts are great and all..but could you make drivable trains..maybe steam trains..that run on coal? and the tender box could be a 6x6 box that can hold coal and wood only..also there could be chest cars..and box cars..that maybe one specific type of car holds a specific item? like refridgerator cars hold food..and mineral cars hold ores and ingots...and people can ride in the passanger cars...expand on this idea?
