LSL Lights

What is the purpose of these? Make pretty colors?

The LSL lights are located so that Amtrak knows they are cut in while operating over their territory. Also, as a reminder to the crew.

Is this a picture of one above the front truck?

Hard to tell from that view, the light looks bluish, white. LSL lights are amber. They are located on each side of the cab just above the front truck. Maybe in that photo the amber cover lens was broken.

The light in the photo appears to me to be a walkway light.

No, the walkway light is in front of it, out of view. I`ve seen these on at night around Bingo on the Tier. Anybody have a close up of one of these lights?

go to jim-frizzel.com and scroll down to his railroad section for goodcloseups ofNS GE units. The first photo of an ex-conrail dash 8, 8315, shows a good view of the LSL light just left of the number board, it is on the side of the cab. there is also a photo of grey ghost GE 9649, the lsl light is just right of the 9 in the road number. On GE units factory equipped with LSL's that is the location. In his Conrail photo section, there is a shot of 6736. The LSL light is located on the sill below the louvered panel just to the right of the step handrail. On EMD units delivered new and on CR units modified to include lsl's, this was the location, always on the sill above the front truck. Though on some CR modified EMD's it was located towards the rear of the cab on that lower sill. The LSL's would generally only be lit when near Amtrak's NEC territory. A road foreman or a mechanical dept. employee must go in the loco cab and unlock a box to switch the cab signals from normal mode to lsl mode. The engineer can switch the lsl off in non cab signal territory with a button on the control stand, but as soon as he hits cab signal territory, they automatically engage and the little amber light outside the cab comes on to let you know.
