The Liberty Limited was a named train on the Pennsylvania Railroad. It ran from Washington D.C. to Chicago, Illinois, through Baltimore, Harrisburg and Pittsburgh. It began running on September 27, 1925, as a replacement for the Washington–Broadway Limited, which had been introduced in 1923. It originally was scheduled to complete its route in 19 hours.
In June 1938 it became one of the original trains making up the Pennsylvania Railroad's "Fleet of Modernism", using modern streamlined lightweight equipment, along with the General, the Broadway Limited and the Spirit of St. Louis. Beside streamlining, its travel time was reduced to 16 hours 25 mins; 30 mins slower than B&O's premier train the Royal Blue. The train consisted of one lounge Car (Drawing-room, three Double Bedrooms, Buffet), a 14 sections heavyweight Pullman sleeper, a 12-5 and a 10-5 lightweight Pullman sleeper, one dining car, one coach with reclining seat which was regularly assigned, an observation car with two master bedrooms, one double bedroom and a buffet lounge. Prime power was PRR K4s, PRR S1 #6100, T1s and diesel engines. Its primary competition were the Baltimore & Ohio's Royal Blue and Capitol Limited.
