I visited a show today and among other stuff, I bought the above mentioned switch. It will not throw the switch at any voltage below 12vac, sometimes not even at 12 volts. I opened it up and fixed a number of gremlins, but after cleaning, resoldering near broken wires, etc., no change. If i physically throw the switch from the underside (removed the bottom plate) or the top side, it will typically jam with just light pressure applied - heavier pressure gets it moving again. The gear on the motor and the rack teeth on the pie-shaped piece o' plastic the motor mates with do not appear to be chewed up, but honestly, my eyes aren't THAT good. I'm guessing a new motor and the pie-shaped piece would fix things right up, but after visiting Lionel's site, I cannot find any parts available - do they still make these switches? And did they drop all replacement parts?

Thanks,

George

Here is the "pie-shaped piece" you are looking for.  It's available for $3.  The DC switch motor is no longer available.

Do you have the ability to provide separate accessory power to the switches instead of using track power?

Here is a link to a Fastrack switch repair that might be helpful.  https://www.youtube.com/watch?v=O9s7wTvwOR0

Thank you, sir! I will order some today, however I would like to know where you came upon the part number? Back before Lionel changed out their website, in particular the parts portion, it was quite easy to find. With this new system, I can find the switch, but I can't find any reference to any parts whatsoever. So, what are you "clicking" on that I am not?

Thanks again,

George

Correct, only using the product number, they do not list for this switch anything https://www.lionelsupport.com/...rol-RH-Switch_681953

However, OK, use the name of what you are looking for not the product number.

Then pick one with a parts listing. Lionel kept the same basic mechanics in Fastrack switches. Yes, electronics are different but the mechanical parts are compatible. https://www.lionelsupport.com/...ol-RH-Switch-6-16827

I watched a Lionel/Mike Reagan video on switches and he stated the Fastrack switches have DC regulators that control the DC to the motor at 5 VDC over the range of inputs (8 - 18 VAC).   If that bit of the electronics is the problem then new motors and gears may not be your solution.   You might want to consider swapping a motor driver board from a good switch to a bad switch to rule out the board.

Thank you much, Vernon! Odd that a system can find something by a description, product number or part number, odder still that there doesn't appear to be any rhyme or reason as to which one will work - sometimes all three, sometimes only one.

Thanks again!

Just to put a cap on this, I examined the gear teeth with a handheld microscope sort of thingy, originally intended to look at phonograph needles. I could see damage to the gear teeth on the motor. Now that I know the part numbers for the segment gear and the motor, it was pretty easy to find them both on Trainz, Both items were listed as NEW, so I'll see what I get in a couple of days.

And a note to Steims, before I bought the segment gear and motor I measured the voltage and it read 4.91 volts at the motor terminals - motor was detached, couldn't really test under a normal load since it was jamming.

Thanks ya'll, good to have helpful support!!!

George
