Yes, that is a bit much. A four car platform uses seven fixtures, we'll assume a 100 watt lamp. To double the length to serve eight cars, we'll need another fourteen fixtures (seven on each side). That's a total of 1,400 watts, or 1.4 KW. In terms of incremental cost, 1.4 KW x 12 hours/day x 10c/KWH x 365 days/year x 200 stations = $800 annually. While the lamps are generally long-life, there is some periodic service and sending out a bucket truck ain't cheap. Night photography is tough in such stations because they use the yellowish high intensity streetlight lamps (I think they're sodium vapor). That is very hard to correct for a natural look. --- SoupGate/W32 v1.03 * Origin: LiveWire BBS -=*=- UseNet FTN Gateway (1:2320/1) |
