I've been a visitor to Mt Martha several times. James has been taught long trains, train cam from me ( in a tiny way
Thr guy who redid the electrical system was going to make provision for DCC at my advice but we never got to it. DC running on ne or two controllers means watching the trains as one always catches up the train ahead.
do a search on mt martha on youtube, you find some of my videos and james's we did several long trains !!!!!!
The railway has WELL laid track allowing trains over 160 wagons if one is mad enough. A good club !
