I have acquired a few of the 42" K-Line O-Gauge (375-376 Models) and have found there are some significant differences in the older Vs Newer.
1st is the Size of the Switch Motors:
The older versions are much larger and use a Coil based Solenoid with (2) incandescent Bulbs for indicators.
The newer ones have an actual Motor driving a Gear and LED Indicators.
Also on the Really Old ones the curved track is full length and the newer (with Big and Small Motor version) seem to have a half length curved track that will require a Half Curve to complete.
I found very little in On-line documentation about servicing these Switches and/or anything about the differences.
Does anyone have a source of Parts Lists / Diagrams / Sources and know where to find any YouTube Videos on servicing?
