Howdy, I just recently bought the #4512 cargo train kit, along with the #4514 cargo crane, and the #10016 tanker car. I've got the track set up in the usual oval form with 6 straight-ways between the curves. While pulling all 7 cars that I've got on the track, it tends to lose it's girp after turning the speed regulator up past the 4th setting. I've got enough of my old train parts that I could build another engine to help with the load, but I was wondering if having two engines on a single track would overload the regulator? I'm planning on getting 2 more cars and a lot more track in about a week, so would adding another engine to my cart be a good idea?
Thanks! Daniel Roberts.
