Here is my problem guys.  I have a BEEP, and it has a rubber tire on one wheel on one side.  When it travels over one particular turnout (the incoming straight in the fork of the turnout) its stops dead at one particular spot.  (Lionel 022 switch)

The reason is, that at this particular spot, the engine is not getting contact with the common outside rail.  This is because the front wheel on that rail has a rubber tire on it, and the thickness of the rubber tire every so slightly causes that side of the engine to lean over to the opposite side. This causes the rear wheel of the engine, on the common rail, to raise up very very slightly, and loose contact with the common rail.  In other words, the loco is perched on three wheels:  the rubber tire on the front common rail, and the two metal wheels on the other side, sitting on the dead rail.

This dead spot, with the wheel above the rail, is only about a half an inch long.  If I reach over and just touch the engine towards the common rail side while it is stalled, the floating wheel makes contact and the loco zooms off.

One solution would be to remove rubber tire from the front wheel of the common side.  This would level out the engine.  But, I use the BEEP as a road engine, to pull 5 cars or so, and I think that without a traction tire, it would not be able to do this.

So, I am searching for a method to raise the surface height of the rail in the dead spot just a little, so that it makes contact with the floating wheel as the engine passes over the switch.

I tried using my crimpers to crimp the top edges of the rail really hard, to squeeze up the surface, but this didn't work.  The wheel still loses contact.

So, what if I laid a thin layer of solder on top of the rail, along that half-inch section, perhaps going past the dead spot by a half inch on each side, and then used emory cloth to sand down any rough areas of the solder, particularly on each end of the solder layer?   

Has anybody every tried something like this?  Should I use tin solder or silver solder?

I thought about cutting the top rounded edge off of a scrap of rail, and then laying a one inch section of that top edge over the dead spot somehow, perhaps "gluing" it down with just a dab of "current carrying" epoxy, but that seems like it would harder than putting down a layer of solder.

Thanks for any input, cautions, experience and advice.

Have you tried adding extra weight to the engine?  I did this on an MTH trolley, and it worked well.  Automotive wheel weights work well, are painted black, have an adhesive backing, and can be mounted either under the engine or inside the body shell.  Just a thought.  I would not go the route of adding solder to the top of the track, as it will make everything else that passes over it look "wonky" -.

It is doable, but not easy. I have an excellent iron and use good solder (Kester). Depending on how thick you need it, it may need to be built up in layers.

It's hard to keep it even, so I  built it up slightly higher than what I actually needed and then did a good bit of grinding  and polishing to get it smooth and even.

How about just swapping the traction tire to the other side ?

Then it would fail going in the other direction!

Hah ! - not necessarily - the OP said that " just touch(ing) the engine towards the common rail side while it is stalled, the floating wheel makes contact and the loco zooms off", so the height differential appears to be miniscule. Allowing for minute tolerances in wheel diameters, rail heights, uneven wheel sets, etc., swapping sides might work.

We'll never know unless he tries it (and hopefully vindicates my suggestion) !

Manny you said "One solution would be to remove rubber tire from the front wheel of the common side.  This would level out the engine.  But, I use the BEEP as a road engine, to pull 5 cars or so, and I think that without a traction tire, it would not be able to do this."  Are you just assuming this would happen or have you actually removed the tire?  Personally I would not make any modifications to that section track but would try some of the engine modifications that have already been suggested.

One of the more valuable lessons I’ve learned over the years - unfortunately, the hard way - is to never make an adjustment to a switch to accommodate one engine if all your other engines pass through with no problem. There are several good suggestions above that don’t require tampering with the switch and those are the ones I’d suggest you focus on.

Robert Buck of York can install a battery powered remote control unit in this piece and your troubles will be totally over.

I had a couple older steam engines which had less than ideal wheel base configurations which now with Battery R/C,  are the most dependable powered units on my roster.

Battery R/C is the future.

IMO, Leave the track alone if every thing else works fine.
