MTH Challenger New Weight transfer Spring:

After some experimentation with weights on top of the front engine to aid traction for the front engine I came up with this setup which is similar to the factory setup/design on the MTH Big Boy. 

The photos should explain most everything.  The plate is made from aluminum and obtained from Lowe's Hardware Store.  The Spring is the same one I used on the Big Boy pilot and is from Ace Hardware and is spring #138(Item#18649).

The setup works excellent and has eliminated the need for the weights on the front engine.  I kept the spring I added on the main pin that connects the front engine to the boiler between but cut it down some to reduce the spring pressure.
