I have an old 4 4 2 steam engine ,Lionel PRR 8304, that because of it's age and old e unit is constantly in motion when the power is on. Is it possible to switch that out with one that has neutral in it? Also a small issue with it going over switches. I have tubular track and it does fine on my 027's and making a turn on my 042's but if I send it straight over my 042's it triggers the e unit to reverse the direction. Your thoughts.

You need to tell us if the engine has an open frame ac motor or dc can motor. Dallee electronics make electronic E units for both that would help you. Your engine product would be helpful.
Possibly this one.
Your locomotive is probably an MPC era one with a 2 position mechanical E-unit. You should be able to replace it with a 3 position E-unit.
The unwanted reversing issue is probably due to poor conductivity, either in the track or in the loco, causing a momentary drop in power that activates the E-unit. Try thoroughly cleaning all the wheels and the rollers, as well as the switch rails, and see if that helps. If not, try locking out the E-unit unless you need to do reversing.
Good luck! Hope this helps.
