Good afternoon,
The good news is that the 90037 set that you have comes with the Version 5 locomotive chassis, so if properly cleaned and lubricated, it should give you good service. Long-term, you will want to plan on replacing your steel track with brass if you plan to run the train year-round; just keep an eye on those curved sections for premature wear. As others have mentioned, a more powerful transformer is also a good idea. The Bridgewerks units are about as good as you can buy, but MRC also makes good units that are easier on the budget. I'm running a no-frills MRC 20-amp transformer that is plenty for most needs. Others will chime in with more options.
Best of luck,
Jay
