dulevoz | Locomotive ASEA ŽRS class 441 - driving the train - train driver view [4K] @dulevoz | Uploaded 1 month ago | Updated 4 days ago
Driving a train from the engine driver's perspective. A few special angles of view to the operations performed by the locomotive driver while driving the passenger train. Preparation for departure, starting the drive, throttle controller for choosing the traction force (selection of current and voltage of traction motors), preparation for braking, direct and indirect train braking process and stopping the train at railway stops and stations.

The ride takes place in locomotive cab of an old diode rectifier locomotive with a voltage selector, and the old throttle manipulator. The throttle manipulator is kind of gas steering wheel for determining the strength of the current on the locomotive's traction motors, which actually represents the traction force. There are also old Erlikon brake levers for train and locomotive brakes.

Don't forget to turn on the subtitle:

"Welcome to the old ASEA ŽRS 441-114 locomotive and its old locomotive cab.
The driver handling the direct brake lever to gradually reduce the locomotive speed in order to approach the train carefully.
Adding traction force to push the bumpers harder and make coupling operations easier. With indirect train brake, it releases air from the main air line to keep the locomotive braked. Shutting down the traction motors rectifier fans, compressor and main switch as preparation for changing the cab and driving direction. There is only one direction lever in these locomotives
and it must be carried out into another cab and used as a cab key to ride.
The video continues from Prisoje station, instead of from Doboj, due to the better light and greater ride dynamics.
Turning on the traction motors rectifier ventilation.
Switching on the main air compressor.
Releasing the locomotive brake and departure...
Using the throttle manipulator as a kind of gas steering wheel for determining the traction motors current strength.
Determining the traction motors voltage level and current strength actually represents the traction force.
Adjusting the limited speed of 30 km/h until the train goes over the switches.
Increasing the current of traction motors and traction force, while accelerating to a maximum speed of 70 km/h.
Around 1000 A current of the traction motors and the train of 2 wagons accelerates very easily.
Final fine-tuning of current size to maintain traction force for a constant speed of 70km/h.
It takes some time to keep a constant movement speed of 70 km/h for a while. A little under 500 A is enough for now.
Soon the train has to be braked due to the passenger train stop.
Handling with indirect train brake handle lever in order to gradually brake and stop the train.
Releasing the brakes, locomotive brake releasing and something not recommended to do while braking, handling the throttle...
The locomotive brakes holds the train braked until the train conductor approves the departure.
The train conductor signaled "Departure" - the foot switch can be used for locomotive horn.
Indicators, viewed from left to right: 1) Manometer gauge for the air pressure in the main air line and in the locomotive main tank.
2) Manometer gauge for air pressure in locomotive brake cylinders
3) Traction motors ammeter (around 400 A is set to maintain the amount of traction force to keep the speed of 70 km/h)
4) Ammeter for the difference in traction motor current sizes (in order to have an insight into possible locomotive wheelslip)
5) The voltage level of the locomotive's accumulator batteries.
Operating with throttle manipulator is operating with voltage selector device. The voltage selector is a large device in the locomotive engine room, in direct connection with the main transformer. The main transformer lowers the 25 kV to a value suitable for the operation of other locomotive devices and traction motors. The main transformer and the voltage selector use the same transformer oil for cooling. The oil is additionally heated in the voltage selector because it is used to extinguish
current arcs while switching from one voltage level to another. Frequent manipulation of the voltage selector heats up the transformer oil and this is one of the reasons why it is not recommended to move the throttle manipulator too often.
Another braking and stopping of the train...
Paying attention to the trackside worker..."

The video was created in the locomotive cabin of an old JŽ locomotive (today a ŽRS locomotive) 441 series, during the passenger train ride on the railway line between Doboj and Banja Luka, Railways of the Republic of Srpska. Date of recording: august 2024.
