Here’s my problem,
I completed my roundhouse and now I’m going to pull the engines in.
With out leaning over and trying to look through the doors or leaving the roof off,
How can I tell when the engine is in all the way w/o going through the back wall?[:)]
For my engine house I used a short section of insulated rail long enough so that the pilot, or tender truck, would close the circuit and light an LED on my contro panel.
Wouldn’t a bumper be the simplest solution?
No room for a bumper!
A insulated section might work, But I have NO control panel & tolerences are very tight.
Maybe a LED over the front doors. hhhhmmmm…

take a look at Block signal detectors (DZ-1011) from Z-stuff ($22 for Two)
they have an adjustable proximity detector with a control wire
the infrared detector will detect the position of the engine and then trigger the control wire that could trip an led or of course change the signal light from Green to RED

I put a microswitch in the end of the track, that turn on the light into the roundhouse. so i know when is the end of track.
good luck
Andre.
I think Andre is on the right track, so to speak. You could use the microswitch to interrupt the track voltage instead, to eliminate your reaction time from the operation. In that case, you would need something like a pushbutton or momentary switch to bypass the microswitch so that you could get out again.
You could use a large (16p) nail as a bumper. Put some heat shrink or foam over it to protect the engine.

I like Andre’s idea with the addition of an overide as suggessted by bob. Just back’em in just in case something were to malfunction when you start them up. Wouldn’t want it to take off suddenly and cra***hru the back of the building
