help me sort this out

LOL...speaking of the 2 speed motors, I swapped in a Power Dash Motor in one of my orange TGV's and he will not stay on the rails. I have to run him on the Lo setting as he fly's off the rails whenever he comes to a curve. I will be replacing the whole motor and housing with a new Shinkansen 2 speed when that project reaches the top of the list. Right now the top of the list is making a Monorail Station and working on video #4.

Looking forward to video number 4, I tried re watching 'bust my boiler' but get this error message now,

   

How annoying!
