Someone brought a working tilt train along to Tony Priestman's Lego Fest
earlier this year. Who was it? I was hoping to have another look at it at
Gosport, but it didn't show.
It worked by having a large bogey pinned upright then pivoted horizontally
onto the rear of one carriage, then also pinned under the front of the next
one. The rear of the carriage was free to both turn and roll, but the pivot
at the front of each carriage was angled, so that the carriage was forced to
roll slightly as it turned into a corner, like a skateboard truck. By only
forcing one end to tilt in this way, with the other end free, it could
easily handle zig-zag tracks and points.
A brilliant (if slightly flimsy) mechanism. I'd like to try one myself if I
could stand to build a diesel :-)
So, come on, who was it?
