Greetings Blog Followers... While I am awaiting the arrival of my track I took the opportunity to run some of my older locomotives and discovered that an old favorite seemed to have lost some power. The locomotive in question is an Athearn SDP40 painted in the New Haven McGuinness livery. For the purists I know that the New Haven never had an SDP40. For the record the EMD SDP40 is similar to the EMD SD45 and the model sits on an SD45 frame. The easy to spot difference between the two is at the rear of the locomotive where the SDP40 has an extended long hood to accommodate a boiler. This particular Athearn model is at least 15 years old. It has the "newer" plastic side frames and gold colored motor with flywheels. Follow along as I inspect, locate and then repair the problem.
The unit has been tested and then retested with it's shell on. The unit is now running extremely well and the head light is bright with no flickering. Remember these are old school units. They simple in design and construction and they are pretty easy to troubleshoot and repair. After a light lube this locomotive is ready for another 15 years of service.
