The expansion pack came with 8 pieces of 18" radius curved and 6 pieces of 9" straight E-Z Track.  I followed the instructions and put the piers at each joint along the track.  I mixed this with the existing track I have which is 12 curved and 5 straight to make a figure 8 over/under set.  After the train would not make it up the bridge, I removed all of the 2 tallest piers and it still wouldn't make it.  The wheels just spin and spin and never get the contact with the track to make it.  Maybe it is just a weak locomotive.  Thanks for the comments.

Hello,

I am a greenie to the model train world and just bought my son the Overland starter HO scale train.  I also bought the figure 8 expansion pack with the pier system to make a bridge.  Once I had it up and running, the train does not have enough power to make it to the top of the bridge, not even without the freight cars attached.  Is this not meant for this train, or is the pier system not meant for any HO train?

Thanks.
