I was looking over a few of the early/mid 90's Lionel Catalogs and forgot about the e units some of the units came in. I have all of the engines from the 90's with Lionel's LIONTECH E-Units. (Dash 8-40 C's/B's, SD-40, etc. The catalogs state you can run these engines equipped with this unit in tandem without locking the reverse unit. Can the engines run back to back, or do they both need to be facing forward for the engines equipped with this unit?
I never tried it yet as my collection is currently being stored. Just curious.
