Challenger/Big Boy Drawbar upgrade:
I found that trying to back heavy, long trains up a steep grade would put cause the factory drawbar to tip down allowing the tender-drawbar peg to come out of the drawbar. To eliminate this issue and also shorten the distance between the engine and tender I made this custom drawbar out of scrap steel.
I replaced the stock spring with a few of the plastic washers that were included in the Kadee 881 adapter package. By using the washers instead of a spring, they help hold the drawbar in place when under heavy load backing up.
Here is the result.
