A mystery explained

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.

    Hi Al. We have those little car’s here.They are not used anymore on rail line’s.But people have saved them from the scrap yard’s and have reconditioned them for there own pleasure and ride used and unused rails for site seeing and such.They like to travel in groups to have fun running the rails.We call them speedsters. Anyone can ride them where allowed.We we sure have a lot of no longer used tracks here.I traveled in one a few times and they really zip along.When we stopped and needed to turn around.Some had that piston and some had an attachment on the front like a jack that lifts the wheels and the just pull it around to the other direction and away they go.

    Yep, an other mistrery resolved. I thought that he had the train going in a circle and just the speed alone kelp it on the rails !! Ha Ha circle Ha ha ha funny fun ops, I will get back to building my tables. Like the light on the end of the car, Bringing the end lights up to date. Question, when did they start using the end car with a battery’s red light??
