It’s a neat alternative to a helix. But, just like he said; it only works for trains with small lengths. It may be be great for narrow gauge, but it wouldn’t totally replace a helix.
Since I’m not a subscriber I don’t get to see it. I had a train elevator that I built on a past layout. It was operated by the use of ropes and pulleys. No motor was involved.
Nicely done within the limits the owner set for himself. It could be expanded - the John Armstrong ‘dehydrated canal lock’ was 16 feet long - and the prohibition on backing moves could be addressed with some rather simple circuitry.
My own elevator will be longer, but straight, and will be operated with a simple lever. As for the stop circuit - would you believe, a diode? of course, the elevator will be single ended, and all movements will be cars first on, locomotive first off.
That’s a great idea! I was thinking about incorperating some kind of lift mechanism to lift the sceincking off of my hidden tracks. Maybe something like this wold work.
