Not sure why you wouldn't want to use the screws?? I like that allot more than soldering!!

For me soldering is a pita! 

Might sort of unsolder itself over time.

It shouldn't but it could. But is it possible is my question? 

You can solder it but it will not last. Note that it is a Nichrome wire so soldering it will be very tough. Also you can guess what will happen when the wire gets hot... I have a first release Allegheny that does the same thing... now where did I put those spare fasteners...

Thank you. In case I lose any, would these work? 

The Lead is not nichrome.  The resistive wiring is and attached to assembly end piece.  MTH Resistor all solder in and so do many other Lionel engines.  So yes you can. G

Cool thanks. Using the screws with those tiny nuts are a royal pita. 

I wondered why they went to the screw fastener method...

Me too. And on the recent legacy engines, there soldered. 

Hmm. Thanks for clarifying... cannot understand why my Allegheny from year 2000 keeps melting its soldered attachment. 

I've soldered tons of smoke resistors in, and other than runaway regulators or shorted triacs cooking them, I've never had the solder melt.

Firgured it was possible. 

Well, if you have the wrong size resistor and draw a lot of current it may be possible, and typically manufactures use a different type of solder for smoke elements.  Higher melting point.  Plus if resistor is too close to joint or a resistive joint, that might do it.  G
