On July 28th, 1939, the Pennsylvania Railroad officially began it’s Trail Blazer service between New York and Chicago via Philadelphia and Pittsburgh. Using existing P70 coaches and other heavyweight cars, the train was streamlined and painted to match the railroads famed Fleet of Modernism consists of the Broadway Limited. Skirting was added along the bottoms of the cars, the roofs were cut down to match the contour of the lightweight Pullmans, and they were painted in the tuscan red with maroon over the windows, along with black handrails and a generous amount of gold pinstriping. The gaps between the cars was completely covered in light gray.

The train was such a success that reservations needed to be made 6 weeks in advance. Originally expected to only be (8) cars long, it quickly became (10), and eventually as much as (14) cars by 1943. It was so popular and profitable, that it carried 35 times more passengers than the Broadway Limited, and in 1940 it grosed over $2.2 million, or $47,900,000 in 2023 dollars! It was also one of the railroad’s heaviest trains, averaging over 1000 tons, and often required double heading. The Trail Blazer ran as #76 eastbound and #77 westbound from July 28, 1939, until July 26, 1959, just 2 days shy of 20 years.

The train comprised of:
PB70ER Baggage-Lounge car – Formerly a PB70 Combine
Multiple P70KR and P70GSR Reclining Coaches – Formerly P70 Coaches
D70CR Full Dining Car – Formerly a D70 Diner
D70DR Kitchen-Crew Dormitory – Former a D70 Diner
POC70R Observation-Diner-Lounge – Formerly a P70 Coach

In 1941, with the success of the Trail Blazer, the PRR began operating The Jeffersonian; a similar deluxe all-coach service from New York to St. Louis, utilizing similar equipment. The train ran as #65 westbound and #64 eastbound from 1941 to 1956.

Locomotives #1120, #2665, #3678 & #5338
In December 1940, K4s engines #1120 and #2665 were selected to be semi-streamlined for the railroads new South Wind train that ran from Chicago to Miami. Unlike the earlier Torpedo engine #3768, these engines had a much simpler streamlined design, consisting of a bullet nose, skyline casting, angle cab walls, pin-striping, and short 110P75 tender. The pin striping under the cab and on the tender lined up with the Fleet of Modernism paint scheme, which provided an aesthetically pleasing continuation from engine to observation car.

Early the next year, K4s engines #3678 and #5338 were given the same streamlining and were assigned to the Jeffersonian. Eventually they saw use on the Trail Blazer, the Broadway Limited (New York to Chicago), the Liberty Limited (Washington to Chicago), and the Cincinnati Limited (New York to Cincinnati). The streamline shrouding was removed by the early 1950s.

None of the (4) K4s were preserved.

The PRR K4s Streamlined set includes: (1) Engine, (1) Tender, (1) Combine, (2) Coaches, (1) Diner, (1) Kitchen/Dorm, (1) Observation
