The first fan trip on the New Haven on the list is the October 6, 1936 run between Boston and Cedar Hill on the Comet which had gone into regular service in June, only a few months before the fan trip. (The Comet was sometimes used for special excursions on Sundays.) In March of the previous year the Railroad Enthusiasts had sponsored a Boston-Nashua trip on the B&M's Flying Yankee which was also new, based on the Burlington's Zephyr and similar to the Comet . Presumably, the first fan trip over the New Haven included a tour of the Cedar Hill Yard. On three previous trips in 1935, the Railroad Enthusiasts visited the American Locomotive Works (ALCO), the NYC's enormous Selkirk Yard near Albany, and the B&A's Springfield Shops.
The next New Haven fan trip was on May 10 and 11, 1936 to Baltimore to visit the B&O's Mt. Clare shops which was building steam locomotives as well as repairing them and was the home of the Baltimore & Ohio's large collection of historic equipment. A New Haven coach was used from Boston to NYC (presumably on a regular train) where the Enthusiasts transferred to a CNJ ferry or B&O bus to reach the B&O in Jersey City.
The third New Haven fan trip on the list was on August 8, 1937 using A-1-a class 4-4-0 number 1281. The train visited the Readville Shops and the Boston Army Supply Base. The 4-4-0 was one of the oldest engines on the roster having been built by Schenectady in 1896. The 4-4-0 type was close to retirement on the New Haven but the B&M used 4-4-0s at North Station for over another decade. The New Haven 4-4-0 was considered an antique at 41 years old but today there are many diesels operating at that age. Below is a photo of 1281 on the August 8, 1937 fan trip while at Dry Dock Avenue on the Boston Army Supply Base.
