The easterly new cantilever in the previous photo is for three tracks (the westbound or main 1, the eastbound or main 2, and the K-line main). The area between the two signal cantilevers appears to be a control point with 4 power switches (a switch from the K-line to main 2, crossover from main 2 to main 1, and switch from main 1 to the yard lead). Each signal appears to have two heads, which is required for today's signal aspects, many of which require two heads to display the proper signal aspect. On the off-chance that you are looking at the fairly wide space between each of the signal foundations and the nearest track, and think that there might be a track missing, keep in mind that today's clearance standards call for 15' clearance from the centerline of the nearest track to the near edge of the signal tower. Practically speaking, although there isn't room for another track, there is room to drive between the track, when occupied by a train, and the foundation. The old cantilever at MP 204.99 probably only had a clearance of about 9 feet to the WB track centerline. Glen Haug

this is the new signal bridge for east bound trains at the west end of south street corssovers as uou can see three lights on the cantilver jgp 2 11-24-11 show the base for the new signal bridge for east bound trains jpg 3 1-24-11 shows the base again with the new sign call out the aera as south street jgp 4 11-24-11 shows three new signal mast for only one signal to be mounted on Bill Ewinger Burlington Iowa I didn't think you you could have a signal for a track that does not exists at the signal.you would have signal light show a diverting track with the signal over the track that has the switch in it [Non-text portions of this message have been removed] __._,_.___
