Sounds like dirty track or possibly a loose connection to the E-Unit coil.
Quiet is fine.
Electrical problems are mechanical in nature... so check your complete circuit to the loco, especially to the E-Unit solenoid. Inspect everything from dirty track, through the rollers & chassis ground, checking for loose connections and cold solder joints, or failed parts.

I've got a really nice Lionel 2020 Turbine- it runs super quiet and smooth,but at times it will stop and reverse by itself. The e-unit cycles properly but is REALLY quiet, almost no buzzing. Any thoughts? I've never seen anything like it.
Gotta love the smell of smoke!
