I did try a search for this info, but found nothing specific, or missed it. Has anybody ever developed a speed control circuit, possibly using a triac, that can be installed in an E unit type Lionel engine, such that it is adjustable so you can set each loco to run at the same speed for multi-unit lash ups? This would compensate for the variations between engine speeds at the same track voltage.

No.

Not a chance.

No-e
OK, well, so much for that idea.
On second thought...I have done a little digging and found that an AC series motor can be controlled with conductive or inductive compensation coils, or a combination of both. I am still trying to dig out how to install them, one type is wound on the stator, the other is not, and to still find out if it would work at all with 16VAC motors. While this would not allow an easy 'turn a control' method of speed control, it would allow you to take the engines you wanted to pair together, compare their speeds at a specific voltage, and then slow the faster loco with these added coils to make it work better with the slower one.
Is this really worth all the trouble?
CAL, see this thread:

I was really just looking for a way to slow postwar steam locos down to "sane" speeds where they wouldn't fly off the table. A variable resistor (rheostat) probably placed in the tender and wired across the motor armature might allow you to fine-tune the speed range. One poster observed improvements but the resistor generated a lot of heat. Something to think about.
I’ve done twin lash ups with postwar engines with no problem and no modifications.
two 2243 run great together
two 2023 Alcos run fine too.
