During a Monday press conference, Eng said he will "work with whatever resources are given" to him. Public transportation experts on Greater Boston said that comment was a red flag.
"If he only has the resources that he has today he will fail because they're not enough," said Jim Aloisi, former Massachusetts transportation secretary.
Aloisi said Eng will need a revised collective bargaining agreement, more money from the legislature and a larger staff.
"What we need to do is to focus on what needs to be done in a candid way and we need to ask the governor and the legislature to take action because Phil Eng won't be able to do it on his own, he has no power," Aloisi said.
Doug Most, author of "The Race Underground: Boston, New York, and the Incredible Rivalry that Built America’ First Subway," agreed with Aloisi.
He said the MBTA was "born broken," designed with narrow tunnels and sharp turns that rule out long trains and fast speeds. "This is something we have to live with. This is what we've got. This is Boston for better or for worse, this is the system we have," Most said.
