Hey Sunrise. Your wish has been granted with the catalog G5s. The Sunrise Special was an interesting operation uring the Roaring Twenties . The Pullman Company took over the operation of the train in 1926 and brought in buffet parlor and club car service on the train. In the remaining years before the stock market crash , Pullman added an open platform Observation buffet lounge. There was also a Parlor car that came from Washington DC. The Consist of train 18 was generally 5-6 cars all Pullman Company operated including the club , parlor cars, the washington parlor a diner and the observation. This cars drumhead was a red keystone with a white outline which had a red pinstripe about middle of the white outline. lettering was PRR style of the day in Gold carrying the trains name Sunrise Special on two lines and below in the bottom on two lines, Long Island Railroad.
Train 18 had a advertised running time from Pennsylvania station to Montauk less than 3hrs , bettering today's schedule. of the Cannonball. It was clearly the way to the Hamptons in those days, Nothing finer on the rails and your twin six Packard or Rolls could not match the amenities.
The G5s used with that special tender might have been LIRR like 21 as shown or PRR leased locos which were used with the tender that carried the spectacular Keystone adorned tender for the train.
Asit is shown in the catalog, 21 needs to have the front mounted airtank which seems to be included on the PRR G5s shown in the Catalog. Charlies number 35 offerring is correct without the air tank up front. Hope this gets back to MTH so that Sunrise Special fans can have a perfect model.
