The October 2016 issue of the Bridge Line Historical Society Bulletin carries a story by W.T. Coniff entitled The Delaware & Hudson [in 1945]. Under passenger service he mentions that "Through Troy the Montreal Limited runs in both directions the year around, as does the southbound Laurentian, which is here combined with the Rutland Railroad's Green Mountain Flyer for movement to New York City. The northward Laurentian is routed through Troy only on the summer schedule, running via Albany from September to June."
