These latter two groups were equipped with the center door cutout feature and indicated by a white line painted under the number outside as an instruction to keep these cars assigned to such services operating to South Ferry, City Hall, and certain shuttle services.

Car 3938 sported a robin egg blue interior paint scheme during the late 1940s.

In 1915, as part of the Dual Contracts expansion, the Composites were completely rebuilt for expanded el service, with new motors, new trucks, and an improved low voltage operating system with the newest AMUE type braking, which was quickly becoming the industry standard.

A run of 478 car bodies were ordered from Pullman, numbered 4037–4514, to be placed on the old Composite trucks.

However, after ordering this equipment, the IRT found itself left with 124 old Composite motors from cars that had never been converted to trailers.

The IRT was reluctant to revert to the older high voltage control system, having successfully used low voltage equipment in their recently put-into-service 12 Steinway Low-V motors for their initial Queens operation, as well as the fleet of rebuilt Composites just transferred to the elevated lines.

Even with this provision, however, all trailers could be freely used in all High-V consists regardless of which assigned fleet of cars.

None of the Hedleys were saved, as it was not thought of at the time to preserve for future generations, although car 3700 was briefly considered for this purpose.
