A model trains railway

Model railway train set.
A huge model train railway layout 1,500 feet long, 14 railway tracks that can run 26 trains at the same time with 106 trucks and 187 coaches all going simultaneously giving a huge running session OO gauge with some HO gauge trains.
105 buildings and hundreds of trees and animals. There is 3 km of wiring with automated signalling. I am not a highly skilled modeler or have a good knowledge of trains, but enjoy making things and driving as many model trains as possible at the same time as realistic train railway speeds. Trains were built to get passengers from A to B as quickly as possible.
