No you cannot bring back the coin nor resources. A similar question has been asked many times on the official TrainStation forum and the answer from the games developers has been that you were rewarded with experience and items for your delivery of resources and coins to the contract stations.

You can use those resources and coins to build decoration and buildings at the stations will result in additional XP being rewarded.
