The couplers used on the subway cars are designated by which symbol?

The couplers used on subway cars are designated by the H2C symbol. This notation indicates the specific type of coupler designed to safely connect multiple subway cars, allowing for efficient operation and maneuverability. The designation itself typically derives from industry standards that classify coupler types based on their design, functionality, and compatibility with vehicle specifications.

In this instance, the H2C coupler is particularly noted for its strength and reliability in urban transit applications, helping to ensure the safe transport of passengers. Understanding these designations is crucial for train operators, as it helps in identifying the proper maintenance practices and the correct procedures for coupling and uncoupling the subway cars.
