3 Throttle Lever The throttle lever actuates switches within the controller to establish low voltage electrical circuits to the engine governor for purposes of controlling engine speed. The throttle has ten positions namely, STOP, IDLE and running speeds 1 through 8 as shown below. Each of these positions is shown in the illuminated indicator in the upper left hand corner of the controller. To stop all engines, the throttle lever is pulled out away from the controller and then moved one step beyond IDLE to the STOP position. The IDLE position is as far forward as the throttle lever can be moved without pulling it away from the controller. Each running notch on the throttle increases the engine speed an average of 84 RPM starting at 315 RPM at IDLE and Run 1 and going to 900 RPM at full throttle. B&SVRR 6540 Orientation Page 3

4 Reverse Lever The reverse lever has three positions: FORWARD, NEUTRAL and REVERSE. Direction in which the locomotive moves is controlled by movement of this lever to the FORWARD or REVERSE position. With the lever in NEUTRAL, no power will be developed if the throttle is opened. The reverse lever should be moved ONLY when the locomotive is standing still, and only after the throttle has been in IDLE position for a few seconds. B&SVRR 6540 Orientation Page 4

6 Cylinder Test Valves Each cylinder is equipped with a test valve for the purpose of testing for fuel or water accumulation in the cylinders prior to starting an engine that has been shut down for a considerable period of time. To make this test open all cylinder test valves approximately 1-2 full turns, and rotate the engine 1-3 complete revolution by pressing the engine start button. If liquid is discharged from any cylinder, investigate; if not, close cylinder test valves and start engine in the usual manner. B&SVRR 6540 Orientation Page 6

7 STARTING THE ENGINE 1. Close throttle. 2. Place reverser handle in Neutral position. 3. Close battery switch in electrical compartment. 4. Close Control switch on engineer control stand. 5. Close Fuel Pump switch on engineer control stand. 6. Open Gen Field switch on engineer control stand. 6. Place Isolation switch at rear of engineroom in Start position. 7. Place Fuel Pump switch in on position. Fuel should show in glass: B&SVRR 6540 Orientation Page 7

SHUTTING DOWN THE LOCOMOTIVE 1. Place Isolation switch in Stop. 2. Stop engine by pressing engine stop button. 3. Turn fuel pump off at engine starting station. 4.

9 SHUTTING DOWN THE LOCOMOTIVE 1. Place Isolation switch in Stop. 2. Stop engine by pressing engine stop button. 3. Turn fuel pump off at engine starting station. 4. Set independent brake. 5. Set hand brake. 6. Turn off all lights. 7. Turn off radio 8. Open main battery switch. 9. Close windows and lock cab 10. Drain air tanks. B&SVRR 6540 Orientation Page 9

ISOLATION SWITCH The isolation switch has two positions, one labeled START / STOP / ISOLATE, the other labeled RUN. The functions of these two positions are as follows: 1.

10 ISOLATION SWITCH The isolation switch has two positions, one labeled START / STOP / ISOLATE, the other labeled RUN. The functions of these two positions are as follows: 1. START / STOP / ISOLATE Position The isolation switch is placed in this position whenever the diesel engine is to be started. The start switch is effective only in this switch position. The START position is also used to isolate the unit, and when isolated the unit will not develop power or respond to the controls. In this event the engine will run at idle speed regardless of throttle position. This position will also silence the alarm bell in the event of a no power or low oil alarm. It will not, however, stop the alarm in the event of a hot engine. 2. RUN Position After the engine has been started, the unit can be placed "on line" by moving the isolation switch to the RUN position. The unit will then respond to control and will develop power in normal operation. B&SVRR 6540 Orientation Page 10

11 LAYSHAFT LEVER The layshaft lever can be used to manually shutdown the engine or to facilitate the starting of a cold engine. Prior to starting a cold engine, push the layshaft lever to admit more fuel into the cylinders. Pull the layshaft lever to shutdown the engine. You can also pull the layshaft lever out all the way when turning over the engine with the cylinder test valves open. This will prevent fuel from entering the cylinders.

THE 24RL BRAKE SYSTEM The automatic brake valve quadrant has six positions: (1) Release: Located to the extreme left, is used to release and recharge the brakes.

12 THE 24RL BRAKE SYSTEM The automatic brake valve quadrant has six positions: (1) Release: Located to the extreme left, is used to release and recharge the brakes. This is not used on the B&SVRR as it can overcharge the trainline. (2) Running: Located at the first detent, is used to release and recharge the brakes. (3) First Service: Area where brake pipe pressure can be reduced to apply train brakes. The independent brake also applies at this time. (4) LAP: is against the leftmost part of the second raised portion and is used to hold the current reduction. (5) Service: Located to the right of Lap. The longer the brake handle is in the position the greater the reduction. (6) Emergency: Located at the extreme right of the quadrant is used for making an emergency brake application. B&SVRR 6540 Orientation Page 12

13 Independent Brake The independent brake has 2 positions: (1) Release: Located to the extreme left, is used to release an engine brake application. An application of the automatic brake also causes the independent to be applied. If the engineer desires to release the engine brakes at this time while keeping the train brakes applied, he presses down on the independent lever. This is called "bailing" the independent, and keeps the engine stretched out from the train. (2) Apply: Located to the right of Release, is used to make an engine brake application. Positions between Release and Apply provide a continuously variable amount of application. B&SVRR 6540 Orientation Page 13

14 CONTROL AND OPERATING SWITCHES A group of three operating switches located at the lower left corner of the control stand. They snap into the on position when moved upward. CONTROL & FUEL PUMP SWITCH Provides power to various low voltage control circuits. The switch must be on to start the engine and operate the fuel pump. ENGINE RUN SWITCH Must be on to obtain control of engine speed. GEN. FIELD SWITCH Must be on to obtain power from the locomotive. B&SVRR 6540 Orientation Page 14

LOW OIL PRESSURE PROTECTION In the event of low oil pressure in the engine lubricating oil system, it will be detected by the governor low oil pressure protective device, which will act to shut down

15 LOW OIL PRESSURE PROTECTION In the event of low oil pressure in the engine lubricating oil system, it will be detected by the governor low oil pressure protective device, which will act to shut down the engine. This device is built into the governor and when tripped, causes a small button to protrude from the front of the governor. The alarm bell will ring and the low oil light will come on. The light will go out when the governor button is manually reset. The alarm can be silenced by placing the isolation switch in start position. B&SVRR 6540 Orientation Page 15

16 OIL LEVEL The engine oil level should be checked with the engine hot and running at idle speed. A dipstick, Fig. 4-4, is located on the right side of the engine and should show a level between "Low" and "Full." When the engine is stopped, the oil in the filter and cooler will drain back into the oil pan. If the oil level is checked with the engine stopped, the reading on the dipstick will be above the FULL mark. B&SVRR 6540 Orientation Page 16

Oil Pressure A lubricating oil pressure gauge is mounted on the engine control panel, Fig. 4-7. Oil pressure at 835 RPM is normally 40 to 50 pounds. It should not drop below 20 pounds.

17 Oil Pressure A lubricating oil pressure gauge is mounted on the engine control panel, Fig Oil pressure at 835 RPM is normally 40 to 50 pounds. It should not drop below 20 pounds. At idle the pressure should be at least 6 pounds. In the event of dangerously low oil pressure the engines will automatically be stopped by action of the governor low oil pressure button.
