How old are your locos? (Years made?)

What cab numbers?

Thanks.

joe,  mpc and post war era.  I hate those old E units, too noisey and un predictable.  I like the williams units. Quite, great for running a block system of multi train operation as one train controls another knowing they will start in forward.  any assistance will be appreciated.          John Cipolla

Dear John,

Are your mechanical e-unit locos noisy in neutral?

I like the idea of the diode and cap on the e-unit coil mentioned here:

                                                       (+)            e-unit
                                                       cap           coil
                                                        (-)              l
                                                         l                l
                                                         l                l
outer-rails, wheels, frame----------------------------l

The old Lionel motors are grounded to the frame, and unless you could electrically isolate them from the frame,

they would not be compatible with an electronic reversing unit.

Hope this helps.

Sincerely,

Joe Satnik

Dear John,

September 1998 Classic Toy Trains pg. 126

has a review for the Dallee line of electronic e-units. 

These can replace the mechanical drum e-units in old Lionel locos

(You must first isolate the motor winding from the frame):

Hope this helps.
