From time to time I go through the locos and check each in wiki if there is requirement for some task. Similarly for wagons. I still keep them if they can't be bought for gold and were a reward. The rest which I can rebuy for gold in shop at any time I sell.

When you are low on storage but don't want to sell, use the depot and most pwoerful locomotives, I primarily put there various passenger wagons and keep in storage only the most profitable ones for immediate use.

Some trains which were rewarded to you can't be sold but most of them can be sold (like achievement unique reward loco) even if they are not in the shop.
