I have recently left a bag behind in a train.

It was a long travel day, and the last stage of it was a train ride with a change half way through. We were in a hurry to catch the connection, and were carrying quite a few bags with us, and somehow managed to leave one of them behind. It was only when we boarded the connecting train when we realized one bag is missing.

We might still be able to retrieve it from the Lost Property, but to avoid such a situation going forward, are there any practical tips, techniques, anything I could use to make sure not to forget any more bags? An obvious idea is to carry less items altogether, but I’d rather hear some suggestions for the scenario when carrying multiple items is already an unavoidable fact.

Note. Although our case is about a train journey, I am interested in tips that would work with other means as well, such as taxis or buses.
