132 Automatic Station Help Needed

If it is wired correctly, this is what should happen.  When the loco hits the insulated track, the voltage passes through an open thermistor.  When the thermistor heats up, it closes and makes contact to complete the circuit and engine should start. 

I'm guessing either bad wiring, or bad/dirty/misaligned thermistor.

You might want to test operation of the thermistor on the bench by hitting either end with some juice from a transformer, to see if it moves.

Something is wired wrong.  The station light should not go out.  When wired correctly it will always see the main track voltage.

Even when set up correctly the station will not work with many modern engines.  But, in that situation the engine will not stop, or it will only slow down.  When an engine enters the insulated center rail section it is still drawing a trickle current through the nichrome wire.  With a post war engine it's not enough current to move, but it will heat the wire.  At some point the contact will close and the engine will receive full power and depart.  The probelm with some modern can motors is the trickle current is enough to run and they won't come to a full stop.

The light in the station is NOT supposed to go out.  Because the load on the power supply goes down when the train stops in the block, the light actually gets a bit brighter.

The bulb(heater too) is powered by wires to Lockon clips 1 & 2 outside the block, the third wire powers the block through the bimetallic strip and contact to Lockon clip 1 inside the block.

K Thanks guys I'm Going town to do some fiddling with it now.
