How many total doors are operated by the operators on R44 and R46 cars?

R44 and R46 subway cars are designed with multiple doors to ensure efficient boarding and alighting of passengers. Each car typically has four doors on each side, amounting to a total of eight doors per car.

When considering a train that consists of a specific number of cars—commonly, a train may have a 2-car configuration for operations, or sometimes more, depending on the service and system needs. In the context of the question, if we assume a typical 2-car trainset configuration, multiplying the number of doors per car (8) by the number of cars (2) results in a total of 16 doors that operators can control.

Thus, the correct response is based on understanding the configuration of these railcars and how many doors are involved in standard operational setups.
