Train-related introductions in 1940

The New South Wales Tulloch suburban carriage stock were a type of electric multiple unit operated by the New South Wales Government Railways and its successors between 1940 and 1992. In their later years, they were nicknamed Red Rattlers.

The British Rail Class 487 electric multiple units were built by English Electric in 1940, for use on the Waterloo & City line.

The R9 was a New York City Subway car model, which was built by the American Car and Foundry Company and the Pressed Steel Car Company in 1940 for the Independent Subway System (IND) and its successors, which included the New York City Board of Transportation and the New York City Transit Authority. Identical to the preceding R7/As, the R9s had distinctive curved ends on the rollsign boxes and contained distinct 2CY air compressors not featured on the older cars in the R1–9 fleet. A total of 153 cars were built, numbered 1650–1802, and arranged as single units. They were the last R1–9 type cars that were ordered before the merger of the IND with the IRT and BMT in 1940.
