In Connecticut, one of the rail trail (which is railbanked) is called the Airline Rail Trail, it was the old Airline Division of the New Haven, which was the Boston and New York Airline. The fastest train between New York and Boston until the late 1990s was the Ghost Train, the New England Limited. It was painted white (even the coal) and it ran at night. Successful, but hard to keep it clean.
Also on the trail is the site of the only 4 train accident in the US. Two passenger trains and two freight trains got together, only two deaths.
