The layout I’m building has a dog leg on which the same track is used both ways on a 6 foot long 2 & 1/2” rise (3.5%?). At the bottom of the grade there is one foot straight with 1/4” drop followed by an O54 curve which drops another 1/2”. The final 20” feet of straight track drop another 1/2” The top of the dog leg is flat wtth some straights and an O31 curve.
I'm concerned that any of my locomotives will pick up too much speed on the down hill section.
I plan on powering 2 main Lines (1948 and 1954 locomotives), a trolley, and various switches and accessories with conventional power (ZW 275 and lionel 1033)
can you suggest any speed control For the down hill run other than manual manipulation
I have considered two unsatisfactory possibilities both of which would require a block with a separate power supply (perhaps a fixed voltage line shared with accessories).
1. It’s an L shaped table I could bring the track down the shorter leg of the table However this would necessitate an impossible 8% grade.
2, Run a downhill line parallel to the uphill line this would lead to a tighter circle at the bottom and gobble up space on the layout The other mainline which does not travel up hill also circles at that end of the table
I’d really like to use the same run of track for both up and down. If I must I’ll control it manually but is their another way?
