In 1935, the Milwaukee Road introduced the original Hiawatha between Chicago and the Twin Cities to great acclaim.

Their equipment included the popular "Tip-Top-Tavern" and the distinctive "Beaver Tail" lounge observation cars.

[3] Breaking with the "Beaver Tail" design, the rear of the Skytop Lounge was 90% glass, with multiple rows of windows reaching up to form the ceiling.

[4] The Milwaukee Road contracted with Pullman-Standard for six sleeping cars based on the parlor-lounge design.

The sleeping cars featured reduced seating in the solarium to make room for eight double bedrooms.

Pullman-Standard delivered the cars between December 1948 and January 1949 for use on the Olympian Hiawatha, which operated between Chicago and Tacoma, Washington.

[7] In 1964 the Milwaukee Road sold all six to the Canadian National Railway (along with six of the Super Domes), which dubbed them "Skyview" lounges and put them into service on the Ocean.

After that venture failed the remains of the cars were purchased by the Milwaukee Road Historical Association in 2009 and shipped to a museum in Montevideo, Minnesota.

187, the Coon Rapids was last spotted around 1979, and is thought to be stored with the last two Baldwin RF-16s in Wells, MI as part of a private collection.
