POST 5:
switch mods:
1. Sometimes there no room for the motorized portion of the switch. It can be mounted under the table but I was too lazy. Some wire and a few screws makes a crude, but effective, ground throw. Some more scale like ground throws can be had from caboose hobbies.
2. These are only toys, not antiques, so some cutting (used a band saw) of the turnout and rotating the cut off piece allowed the next spur track to be much closer to the straight track route.
