| This is the lower level view of the wire train. During normal operation with the passenger train sets, this would be the regular hangout for the car knockers - they do their running gear inspections (brakes, wheels, etc.) with pretty much everything at eye level. Notice also the red (unlit), green and blue globe lights all over the place. The red lights flash (strobe) when the main (inside) catenary is energized. The green lights (when illuminated) indicate the main (inside) catenary is off and the blue lights provide the blue flag indication. The combination illustrated here (red off, green on, blue on) is the "go to work" signal for the S&I staff. |
