Hi, I have a grade on my layout that runs between three to five percent. All of my MTH steam engines that have the old anaconda type of tender to engine interface run perfect on it. But, it seems that my new MTH steam engines that use the draw bar interface all have had problems with even a three percent grade.
I even had a problem with my George Washington general on a 2 percent grade. It just stopped dead on a flat bridge. A little push up on the connection under the tender and it starts right up.
I make sure that I get a good set when I connect the tender. In other words a gentle but firm push to get that home snap on the Draw Bar connector .
I tried to e-mail MTH on the subject of recommended grade limitations but they don't seem to wont to talk to me. So I was wondering if any one else has been having this problem.
All of my MTH diesel engines pull like a champ on the grade, even with ten or more cars behind them. My old Anaconda Steamers can handle ten freight and about four passenger cars with no problem but my new Draw Bar engines have trouble pulling it's own tender up the grade.
I can only conclude that the Drawbar is where the problem is at. What do you think?
