Looked at areas on the lower level that will be covered by the upper level to see where plywood could be removed to allow access to the upper level for wiring and possibly a pop-up, and provide access to hidden track in case of the inevitable derailment. Took measurements for the abutment supporting the twin bridges opposite the trestle (a keystone in locating pieces of the upper level) and sketched it out.
Here's a pic of the twin bridges from our old layout.
A pic from the old layout of the trestle after the bridges. Ted was pulling a very, very heavy caboose that evening.
