The R28 was a New York City Subway car built in 1960 and 1961 by American Car and Foundry (ACF).[1] They were a "follow-up" or supplemental stock for the "A" Division's R26s and closely resemble them. The average car cost per R28 was $114,495.[2] They operated on the IRT Division (also known as the A Division) in married pairs.

By 1982, all R28s had received air conditioning as part of a retrofitting program. The R28 cars were rebuilt between 1985 and 1987 and repainted into Redbirds by Morrison Knudsen in Hornell, New York, which extended their service lives. They were last in service operating on the 2 and 5 services before being retired in October 2002.

Retirements, scrapping and preservation

The R142 and R142A car orders replaced the entire R28 fleet.

Today, cars 7924-7925 and 7926-7927 survive. 7924-7925 are still on the New York City Subway property, and were used for work service until July 2013, when the pair was moved to Concourse Yard. 7926-7927 are currently in the Illinois Railway Museum collection undergoing restoration.

These were the last ever passenger cars built by ACF, with the final cars delivered in January 1961[3] with the closure of the Berwick assembly plant. ACF has since continued to focus on freight rolling stock.

Route assignment history

Note; All cars became General Electric (GE) cars and became permanently paired with link bars after rebuilding.
