I am looking at two versions of the Pennsylvania's streamlined K4. One is an MTH and the other is a Lionel. I am more interested in running the loco than in minute detailing. I like Magne-traction more than Traction Tires. What are the pros and cons of each loco ?
The Lionel is 18052 PRR 238E K-4
The MTH is 30-118-1 Pennsylvania K-4s
