Answer 1

The device used for uncoupling cars in the R44 and R46 trains is called a coupler. Couplers are mechanical devices that connect and disconnect train cars.

Step-by-step explanation:

The device used for uncoupling cars in the R44 and R46 trains is called a coupler. Couplers are mechanical devices that connect and disconnect train cars. They are designed to safely couple and uncouple cars while the train is in motion or at a standstill.

The coupler on the R44 and R46 trains is a type of knuckle coupler. A knuckle coupler consists of two mating parts that interlock when the cars are coupled together. The uncoupling process involves releasing the interlock mechanism to disconnect the cars.

It is important to note that the process of uncoupling cars is typically carried out by trained personnel and follows specific safety protocols to prevent accidents or damage to the train.
