Michael H. Mulhern, general manager of the Massachusetts Bay Transportation Authority (MBTA), wrote a letter to Amorello last week urging the Turnpike Authority not to take action “without the benefit of input from any other city or state agencies.”

The MBTA, which runs the T and the area’s commuter rail system, has a stake in the land because many of the transportation agency’s trains are stored on the Allston parcel during the day.

Besides the many champions of keeping CSX in Boston, some politicians have been vocally advocating for Houghton Chemical, a small, local company that uses the railways and sits partially on land that is soon to be part of Harvard’s domain.

State Senator Stephen A. Tolman, one of several supporters of the chemical company, wrote a letter to the MTA in late March on Houghton Chemical’s behalf.

Yesterday, he expressed disappointment that the MTA board voted despite the concerns of local politicians.

“It would have been my hope that many of the questions and issues surrounding to the property would be resolved before this was rushed to a vote,” he added. “The problem is that Harvard is so powerful…that no one can compete with them.”
