Y2Julio Posted September 9, 2009 Share #3 Posted September 9, 2009 The 3 yellow light bulbs you see on the platforms is to notify the crew of that train to hold the train in the station for whatever reason the train dispatcher wants, be it if the train is early or they want the train to make a connection with an arriving train across the platform. In the terminals, those lights are green which tell the crew to go ahead and depart the terminal. The 4 light bulbs you see are temporary lighting that the MOW people add to the areas in which they are working in so that they can see the tracks better.

Julio, the bank lights have 5 bulbs, not 4 but I think that was the item in question. And boy do those things get hot when they are in use.

Alex L. Posted September 10, 2009 Share #7 Posted September 10, 2009 ah, never really counted them all but I assumed that was what he was referring to. No need to count - they work off the third rail. 600v/120v = 5 Link to comment Share on other sites More sharing options...
INDman Posted September 10, 2009 Share #8 Posted September 10, 2009 No need to count - they work off the third rail. 600v/120v = 5 Now when they set up for something like a "chip out" and the tunnel is filled with bank lights, what do they power them from? Do they tie in to the nearest 3rd rail that remains on? Link to comment Share on other sites More sharing options...
Rapid Transit TO Posted September 11, 2009 Share #9 Posted September 11, 2009 Do they tie in to the nearest 3rd rail that remains on? Yes, they have big spring clips that 'bite' onto a lip on the 3rd rail.. Link to comment Share on other sites More sharing options...
INDman Posted September 11, 2009 Share #10 Posted September 11, 2009 Yes, they have big spring clips that 'bite' onto a lip on the 3rd rail.. Even when they have a tunnel full of them during a GO? I know that how they do it when they put up 1 or 2. Link to comment Share on other sites More sharing options...
Westside Posted September 15, 2009 Share #11 Posted September 15, 2009 Even when they have a tunnel full of them during a GO? I know that how they do it when they put up 1 or 2. For large tunnel sections they will wire the lights together and power them from an adjacent tracks 3rd rail. Heavy gauge clips to an electrical box with a on/off switch Link to comment Share on other sites More sharing options...
