A Boston lawyer says the T and Keolis owe commuter-rail riders a lot more than just a 15% discount on their Mass passes, so, of course, he's filed a lawsuit.

The suit, filed earlier this week in Middlesex Superior Court by Robert Richardson, seeks to make Raquel Rodriguez, identified as "a resident of the Commonwealth," lead plaintiff in an action seeking not just refunds for January, February and March passholders, but damages as well.

Although the complaint does not say which line Rodriguez rides, it does state she usually took an 8:40 a.m. train but during the snow crisis was forced to choose between a 7 a.m. train - too early because she had to get her children to school at 7:30 a.m. - and a 10:50 a.m. train - too late because she would get to work her normal starting time and be fired.

The complaint accuses the T and Keolis of breach of contract for failing to honor rider needs for decent daily service in those months and accuses the authority and the rail company of being "unjustly enriched by keeping the hundreds of dollars Plaintiff and putative Plaintiffs paid the defendants for commuter rail monthly passes for parts of January and March, 2015 and all of February, 2015, when Defendants failed to provide timely and reliable commuter rail service."
