Running O gauge gear on O27 Track

Your 1662 is a prewar 027 engine, not "O" gauge.
There was no such thing as an uncoupling magnet when it was made.
There are a number of 027 locomotives, both prewar and postwar that have problems with electromagnetic uncoupling tracks and later style switches.

So any solutions? I was looking at the O gauge remote uncoupling operating track, and it appears that Lionel solved the problem (or avoided it) by using that big round red insulation piece on top of the electromagnet.

So has anybody tried any mods to the 6019? Like using a Dremel to shave the sides of the oval shaped center rail that curves around both sides of the electromagnet? Or perhaps to leave the oval shaped rail in place and making 4 cuts to electrically isolate it? Or stealing parts from an O gauge remote to use on the 6019, like the red disk? Or just making one out of something? Surely others must have tried some wacky stuff????

My solution is to have a loop of track with no switches or uncoupling tracks. The engines with clearance problems are restricted to that track.
