I am having trouble with my HO engines and cars jumping the EZ track when they cross over the crossing track. Any help I can get would be appreciated.

Are there replacement parts for manual turnouts, the (switch machine) that operates the track direction when the Directional Box button is operated?

HO Bachmann E-Z Nickel silver track. All my turnouts are basic types with plastic frogs, except for my #5 Wye Turnout which has a metal frog, and is electrically gapped (Bachmann does not make a non-gapped type that I can find). I run both analog and DCC engines.  I have a problem with engines stopping when they cross the  #5 Wye Turnout.
