DCist noticed early this morning at New York’s Penn Station that Amtrak is instituting a two-bag carry-on rule starting this November. So if you’re planning any shopping excursions or moving a lot of baggage while taking the train, be ready to check some bags. But we wonder how Amtrak is going to enforce this rule. Are they going to copy the airlines by bringing in little “check the size of my bag” contraptions? Aren’t conductors already occupied by checking tickets? It seems that checking how many bags are in the overhead racks would be counterproductive. Perhaps it is just a courtesy regulation.

This seems to be another sign that Amtrak is attempting to make its service better. Just last month, Amtrak announced that it was doing away with bulk-mail transport, something that it said slowed its service.

(And don’t fear, DCist is not becoming bi-metropolitan. We were just in New York for an extended weekend.)
