Hi guys,
A few of you on the forum have enjoyed the old streamliner Lionel locos. I have a nice 1668E (a 2-6-2 config), and have been peeking on ebay at the somewhat similar 1688's and 1688E's (both simpler 2-4-2 configs with simpler drive rods).
The 1688E has a conventional reversing e-unit.
I'm not sure if the 1688 (rather than the 1688E) has an e-unit or not. It does have a toggle on the top of the loco, but is this simply a switch to manually change direction???
I've been confused that some 1688's appear to have black plastic engines, and others have traditional engines with "conventional" electrical pickups. I wondered why, and assumed (naively) that the ones with the plastic were simply engines that were replaced by an owner somewhere along the line.
However ...
I've just noticed that the 1688's with plastic engines have the slot for the reverse switch (or e-unit?) well aft on the shell, and the 1688's with the traditional engines have the slot for the switch about mid-length on the shell. I.e., they do NOT share the same exact shell casting. Accordingly, they must have been made each differently, each with their own type of engine.
I'm raising this point here for a couple of reasons ...
1. To give a heads-up for anyone looking for parts to repair / service a 1688 down the road ... there are "two types" of 1688's, as far as I can see.
2. To ask any/all of you if you can elaborate on this and/or clarify my findings.
3. Can anyone tell me which of the "two types" of 1688's came first? Why did Lionel change how they were made?
The pics below show the two types of 1688's.
Also, as far as I can see, ALL of the 1688E's (the one that came with e-units for sure) have the slot mid-length on the shell, and all have conventional (non-plastic) motors.
Note, importantly, that the 1668E (which looks very similar to the 1688 family at first glance) is a 2-6-2 config, has more elagant drive rods and valve rods, and has its e-unit slot well forward on the shell.
I'd welcome any clarifying thoughts.

1688 TYPE #1 -- SWITCH SLOT MID-LENGTH
NOTE CONVENTIONAL MOTOR (though the contact shoes are missing on this one)
1688 TYPE #2 -- SWITCH SLOT WELL AFT
NOTE PLASTIC MOTOR
(THE REAR TRUCK IS MISSING FROM THIS LOCO ... IT SHOULD BE A 2-4-2 CONFIG.)
FOR COMPARISON, HERE'S THE 1688E
WITH E-UNIT, SLOT MID-LENGTH, CONVENTIONAL MOTOR
FOR COMPARISON, ONLY, HERE'S THE 2-6-2 1668E
NOTE E-UNIT WELL FORWARD ON SHELL.
