... Hello John Sorry for the late reply and thank you for the various explanations of the logic behind the changes Here's a small update of a bit of progress on the line under the station. This is the copper paxolin rail support for the doorway bridge. This where trains leap into the air... For some understanding of what I'm saying keep going.... 2787_221930_560000000.jpg And here it is installed in place on the end of the track bed already gapped ready to accept the rails that will be soldered to the copper 2787_221935_530000000.jpg And here we are looking at the "precipice" with some track just laid in place to give the idea of what I'm doing or rather trying to do. 2787_221937_410000000.jpg That's it for tonight. Kind regards Andrew posted: 23 Nov 2020 06:04 from: Andrew Barrowman Hi Andrew, I have done something similar and I also soldered brass tubes to the copper that accepted pieces of 1/8" diameter piano wire. They were inserted into the tubes to keep the rail aligned when the bridge was closed. Cheers ...
