Thanks for all the comments. That's an old picture. I have upgraded my tie downs. The Craftsman GT5000 has very little engine brake on level ground and none down grade. That's why I bought the BX, the right tool for the right job. The BX stops any load I will pull just by letting off the forward pedal. It does work extremely well and the hills I mentioned aren't mountain passes, just grades. I didn't start out with a full load on a ski slope, I added weight over many rides to see what I felt comfortable with. There are anywhere from 10 to 16 wheels carrying this low speed train so the weight is well distributed and doesn't exceed wheel or trailer capacity. Have you ever seen the little 300 lb riding lawnmowers pulling 10 barrels of kids on casters for wheels at fairs. I weighed the BX with the train nose and it's over 2000 lbs. Which would you rather let your kids ride? A lot of times I'll have a trainload of grownups only. Kids at heart. I'd even let Rooster and his lawyer buddies ride.
