Great layout! I bet its fun working out the timings at the crossings!

Back in the 1980's I created a 4'x5' HO traction layout similar to this track plan the main difference being that it had no turnouts. It consisted of one continuous track in a 3 leaf cloverleaf similar to this. As best as I could figure total continuous track length was close to about 40 feet. To simulate streetcar track I used Shinohara double guard rail flex track with black card stock between the inner guard rails and outside the outer guard rails to simulate pavement. Traction consisted of Bachmann trolleys and PCCs and AHM LRVs. I could run 12 cars without them hitting the car in front of it. This was accomplished with small inexpensive 12 VDC relays I bought at a surplus outlet. The relays were triggered by small glass reed switches embedded in the track under the card stock. The switches were triggered by magnets mounted under the cars. I don't remember the exact details but it worked something like this. As a car left a block it shut off power to that block. The following car would enter the dead block and stop preventing it from entering the next block and hitting the car in front of it. As the first car left the block it was in it would again turn off the power to the block it was leaving AND restore power to the block behind that so the car in it would now travel to the block ahead which was now dead UNLESS the first car was now in another block ahead. Bottom line is that no car could proceed to the next block if it were occupied. Once the car in the occupied block left it could proceed to that block. I hope I am making my self clear. But the most interesting part was the center crossing. Using the same type of relays, reed switches and magnets it was set up that no car could enter the crossing if another car was already in it crossing perpendicular to it. It was quite complex but it worked with never a miss. It really was something to see. People would ask me how it worked. I had a police officer figure in the center of the crossing and I would tell people that he controlled it all. When they would scoff I would say I'll show you. I would reach over and remove him at the same time flipping a hidden switch under the layout shutting off the power to the relays. All the cars would start crashing into each other. It was funny to watch people start yelling, no, stop! Overall there were about 50 relays used. The biggest problem was the amount of power needed to power all the cars and the relays. If my skills were better I guess I could have done it with solid state electronics but I never mastered it. I wish I had video of it but it was before the time of inexpensive video cameras. It sits in the garage now as thoughts of restoring it fade with time.

😍😍😍😍

Which wheels on each type are picking up current? Thanks.

help! please tell me how to contact onetrue for advice. am thinking about a unitram V60 starter set x 2. and connecting them as simply as possible via electric switch turnouts? thinking 2 v60s since that might be more interesting then 1 set and simplest way to achieve. have looked at infinite # web pages and videos but cannot wrap my mind around how to. and want usa versions where possible. am senior/senior person with all my faculties working. thanks,

Nice layout ! How about using DCC digits decoders inside of the trams allowing you to run lash ups and multiple trams on the same track?

Gotta have these haha...true, much more fun to watch these than watching my tropical fish, they never collide haha. However, it seems these products never really made their way to Europe. At least I’ve never seen these in specialised model railway shops in Holland that is. Greetings from Hekelingen, Holland. Willem.

ChinaAl, I posted detailed answers and photo to your layout questions on JNS forum/Trams.../UNITRAM Tram Turnout Tests.

Great video. Are any of these trams still available?
