Problems with virginia & truckee HO

Hi out there! I wonder if anybody could guide me in the process of fixing my model. It was a gift from my son but in the delivery process one part broke (it seems to be the one between the coal car and the engine) and I just can’t figure it out how to fix it. Any sugestions?

Thank you.

P.D. My son went to the Walthers site but they couldn’t give him any information

Please try the Model Rairoad section as they deal with H.O. trains exclusively! Much success with getting that item fixed.
