Remaking of the Ridley Keystone & Mountain

[tompm]

In order to determine the amount of shims I need to place under the bridges to reach the track I used double sided tape to attach the track to the thru girder bridge.



You can see from below how much is needed.



I used some leftover roadbed material and cardboard to fill in the gap.



Now I do the same for the two track bridge.



I remove the temporary shims and replace with 1/4 inch foam boards.



Trim the foam board to fit.
