Very nice! That class of 1984-built GP40-2s (the last ones SP ordered) are my favorites! Gotta love the Osciltrol "poor-mans Gyralite" light pacakge up top!
What is the normal gyralight package if this is inferior? I didn't know there was a difference. Thanks.
I believe Oscitrol did not have moving parts like a Gyralite so in theory did not require as much maintenance. It simulated a moving light.
Yep, Russell summed it up. The Osciltrol lights used a pair of lamps set slightly askew ("cross-eyed") that, when activated, flashed alternately, simulating a Gyralite or Mars-brand light (at least in theory). No moving parts to maintain, unlike a Mars or Grya, and some of SP's new and rebuilt power (late SD45Rs, late GP40-2s, and B36-7s) had these instead of Gyralites. These were SP's last fling with warning lights before they were all phased out in favor of el cheapo "gumball machine" flasher beacons on the roof.

Are the Oscilitrol lites the ones that are side-by side, or the unlit one atop the nose lites? If not, what's the unlit one do?
Hemi The ones between the number boards are the Oscilitrol, the one above the headlights is a red UDE lite, or Undesired Emergency lite. And below that is the headlights. The UDE came on when the train went into emergency. Thom
