SP 5623
Cab Details

All 8 of the S.P. and 4 of the T&NO passenger geeps came equipped with dual controls. They had duplicate controls on each side of the cab so the locomotive could be run comfortably in either direction. For a 360 degree view of the cab, taken by Trainweb at Railfair '99, click here.

This is the engineers seat. What else is there to say about that? The handle sticking out in the left lower corner of the photo is the automatic (train) brake.

The 5623 is equipped with the "drum" type controller found on EMD locomotives since the 1930's. It was not until about 1959 that the "AAR" control stand replaced the drum and the stand to the left of it. The drum contains the selector switch (top left), throttle (top right) and reverser (center). The selector switch had many functions over the years but now, it is mainly used to control the strength of the dynamic brake - which the 5623 does not have. The box to the right of the controller is the engineer's cab heater, installed during the GRIP upgrade in 1977and behind the controller is the Barco mechanical speedometer.

The control stand has, at the bottom of the photo, all of the switches required by the lights and the control of the locomotive. The row of colored lenses are warning lights for various purposes and the gauges are for the main air reservoir and brakes. At the left top is the Gyrolight control and below it, a couple of indicator lights for the red warning light and the sanders.

On top of the control stand is the ammeter which, by the way, shows the current being consumed by 1 traction motor. On top of the ammeter is the non-original 96 channel radio. A telemetry (FRED) receiver is mounted on a bracket to the right of the ammeter. The two wooden handles visible to the right of the stand are for the horn. One valve admits air through the horn through a restriction (choke) and gives a muted horn sound.

Below the switches is mounted the independent (engine) brake valve. To its right is the bell valve and to its left is the sander switch. The valve near the floor is called a "dual ported cut-out cock" and is used to test the independent brake system.

This is the fireman's side, where the other control stand used to be. To the left is the other cab heater. To the right is the control head for our auxiliary radio which we keep tuned to our private channel. The blue box behind the radio is the water cooler. To the left of the left hand seat is the fireman's side cab heater. Over the top of the water cooler, on the right is the conductor's emergency brake valve.

In the center of the photo is the control head for the original S.P. 4 channel Micor radio. The radio itself is mounted in the nose. On the right side of the head are, top to bottom, a blue transmit indicator light, dispatcher tone 1 and tone 2 send buttons, the channel selector switch and the volume control. Most of the face of the head is occupied by a speaker, even though the handset includes one. The transmit button is part of the handset.

On the cab back wall are mounted a number of gauges and control switches. These three are boiler water level, control air pressure and engine temperature. In the other photo are the battery ammeter, alarm lights, headlight control switch, isolation switch and miscellaneous switches.

The left photo shows the brakeman's seat and the fusee (flare) holder. The original seat was removed when the dual controls were taken out in 1977. This seat came out of a S.P. passenger SD9. Ten points off for authenticity. The front wall of the cab is occupied by the access doors to the boiler controls and the door to the nose (on the right). The two gauges visible are for boiler pressure and steam line pressure. The all important FRA blue card is in its holder below the gauges.

Inside the boiler doors are a bewildering array of gauges, valves, pumps and electrical gadgets. At the top of the photo are the same two gauges seen in the right hand photo above. The other photo is taken through the nose door. Nearest the camera on the right is a 72 to 12 volt converter I installed for various uses. Behind and above that is the Micor radio pack. Above that is a filter system for the telemetry receiver.

Below is a polaroid I took of the lettering on a piece of metal from the front cab wall.  It is interesting in that the number "3109" appears.  This must have been an error by the stencil maker during the 1977 GRIP rebuild.  When we got the locomotive, the lettering had been painted over.  Locomotive numbers are usually painted on the cab interior, in view of the crew, so they know which locomotive they are using.
