“As an absolute first starter,the basic layout I’m trying to operate uses modern Hornby track. However, the locos are all 60s-early 70s Triang. When I fix 2 Hornby r8201 connectors from the main line to the siding track the locos run for a few secs then become inoperative. I’m concerned I may damage them. What causes this and how do I fix it?”
