I have an older two truck shay.  I just had Bachmann service replace the original trucks with the updated ones.  I want to install a polarity switch into the loco so I can either change directions or disable to power to it (three way switch).  Any suggestions would be appreciated.

Thanks

Hi,  John.

Some LS locos already have a polarity switch in them.  They might have a dead spot in the middle of the polarity switch's throw that would kill the power.

If not, this Radio Shack 275-0664 6 Amp Center-Off switch should work:

If you need wiring instructions, let me know.

Hope this helps.

Sincerely,

Joe Satnik

If your loco is too heavy to lift, you'd better be able to ride in, on or behind it.
