Newby here.
I've been running an older Model Power #6730 Santa Fe F3 locomotive, along with a matching dummy, for some time with my grandson and we have a good time. I found a few more cars at a local garage sale that fit with what I had so I added them. I decided that I'd like a little more power to pull everything so I bought a "B" unit, Model Power #840 A, off eBay. Now I have a problem for which I'm hoping someone can provide a solution or some insight.
1) When both engines are on the track but uncoupled, the F3 takes off and gets to a pretty good speed before the "B" engine starts moving.
2)Once the "B" engine starts moving, it will not run at the same speed as the F3.
3)When coupled together, the F3 strains just trying to pull the "B" engine alone.
I did notice that when I put the "B" engine on the track for the first time and ran it across a re-railer, there was a lot of resistance to rolling free as compared to my 6730 F3.
What can anyone tell me about the compatibility of these two? Any chance I receive "B" engine that left the manufacturer with some defects? With the "B" in the full train; nothing moves. Any information will be appreciated.
Thanks,
