I got a great deal on a 746 that showed some promise with some much needed TLC. I took her all apart, cleaned, lubed, and serviced her. The only thing I was short was the darn expensive L19 bulb. I put her on the track before replacing the shell to perform a test run around the track, but my main line was occupied by my 2500 series set. No problem, I'll just couple them up and take them for a spin. Well, she tried and tried to pull the set, but just kept spinning her wheels.
I can't believe one of Lionel's premium locomotives wouldn't be able to pull the 2500 series set. Okay, it's been a while since the 2500 series set has been in for service, so I clean the wheels and apply a drop of oil on the axles. I get everything ready for the test run, and still, she slips like crazy! How maddening. Next, I spend way to much time meticulously cleaning the track on the main line. Still slippage!
I think of all the things you guys would recommend here:
*Check/replace traction tires (Not applicable)
*Magnetraction - using tubular - seems strong
*Service Motor - well, I just did
*Add weights
And then it dawned on me - the HEAVY shell was not on!
I put the shell on and now she overcame the challenge of the 2500 series set!
