After restoring 18, levers 16, 17, 33 are still free and lever 19 is locked only by 17. Lever 14 is now locked normal via bar 2 in channel 5. At this point the signalman would replace 16, 17, 19 and 33 to permit traffic to pass on the main line but we'll just send the engine on now. The lever leads are a reminder to the signalman about the pulling sequence. Click here to pull 15.
