Ref JIM Z: "I noticed the use of the trestle set on your return loop. Do you experience any great speed build up on the downward leg and will this lead to catastrophic derailments?"
Yes, this is the standard Gilbert trestle set. My experience is:
- Conventional AC engines: I am right on the throttle 'boosting' voltage going up to maintain speed and as soon as the loco heads down, I ease the throttle back to avoid overspeeding. Easy to do though standing right at the Z4000 throttles on my layout ... I throttle back a bit just before heading downward then ease the throttle back some more as the loco gets on the downslope then advance the throttle again as the loco levels out on the main flat layout.
- Constant Speed Lionel Legacy/FlyerChief, or MTH Protosound engines: A real delight as the loco electronics maintain their speed going up, coming down, and going around my reverse loops. No need to nurse 'em with the Z4000 throttles.

Tom
