That is correct.The N indicates that the turnout is the "new" (as of around the early 1980s) model with an EPL drive motor. The original electric turnouts had twin coil switch machines.
Yes, but the upgrade was from the twin coil drive to the EPL drive, not an unpgrade from manual to electric.Like I said back in my post above, when I purchased the LGB switches from Watts Train Shop years ago they said that they were upgrading the switches to the new EPL switch machines and thus the N was added to the model number on the box.
Do you still have those turnouts?For some reason I ended up with four of the old type switch machines that I have never used and are new, I think Watts just gave them to me because they didn't want them and everything was going to EPL and they had no use for them.
As KRS said, LGB never sold manual R3 points.changed the number on the box and added the N.
