I used R1's before I double tracked my garden line (a reverser for my steam tram). The PCC car negotiates R1's OK on my trailer set-up.I am planning a street area and have a pcc trolley, as it is single ended, I want to lay a reversing triangle for it, anyone done this or suggest the smallest radius for the turnouts?.
If you are DCC this may help, I used LGB R1's for the temporary lash up. Just about right I would say for a PCC.I am planning a street area and have a pcc trolley, as it is single ended, I want to lay a reversing triangle for it, anyone done this or suggest the smallest radius for the turnouts?.
Looking good. Such was the swept path (Kinetic Envelope) of long bogie cars, that white line were painted on the road to denote this! On twin track routes, often (on curves) the track were relocated further apart or - in the worst of cases - not allowed to pass on bends!I decided to experiment with some very flexible track, after contacting a chap in Italy about his ho trolley layout and finding he used 4 inch radius track I decided by quick maths that 3 x 4 is 12 bent some rail following the home made compass line, it was a pain bending but once started was easier, next time I will start the bend in the middle and work outwards,
The trolley ran perfectly around the test track so spurred on I will continue, I want it to curve around a garage that I scratched together, based on a one in CornwallView attachment 220792 View attachment 220792 View attachment 220795 uk

or that, I got the car going around a 12 inch radius without too much overhang, but I may ease that to 15 inches I have given up trying to fit in a reversing triangle as its too much track in this area so a balloon loop looks to be the way forward,R1 equals a 14.4m radius curve in 1:24 scale, near enough to a typical tramway street corner. Some Australian systems had curves as tight as 10 meters in places, in 1:24 scale that's only 416mm!
Fantastic - look at:
- The swing on those bogies
- The camber on the roads
- The dent in the front of the PCC car
- The woman standing in the middle of the road by the underpass to catch it
I thought the ones I have seen in museums looked a bit on the narrow side, so that explains that then!I have been told that because of a combination of some very tight radius corners, standard gauge track but almost narrow gauge trams (the Brisbane City Council restricted the maximum width of any tram to 7'8"!),
