Thanks to everyone who mailed in and posted on the mysterious floating train.
I could post a number of replies (thanks everyone) but I’ll just go with this one:
“It’s called a motor car turntable for obviously turning inspection and maintenance vehicles around. It’s basically centered single hydraulic piston jack mounted in the frame of the car with a steel plate that makes contact with the ties/sleepers. This jack lifts the car enough over the rail so the equipment can be turned around.
If you missed Kim’s “how to” on his LEDs it’s here. Here’s his latest:
“Hi Al. Not the best I have made.But with that little board can make an end train device.I have snipped off the led and left the posts. I added a old computer connector on the posts. That is in case the led fails and all I have to do is slip another end train device with a fresh led into the body and connecting to the connector.The 1.5 battery will last along time before it drains. The board has a micro switch you can flip off. I may shrink the device even smaller with a 1.8 mm led instead. But just to show what can be built using that board.
Keep ’em coming.
