The displays also seem to get confused when trains are running on alternate tracks - the northbound 34th/6th one kept pointing to the express track for the D, when it would be coming in on the local track (and at that spot it is impossible to switch). I thought the system, while "off the shelf", was still more precise than this. This can't be that hard: -They have transponders on the tracks and trains -The one on the train tells the one on the track what it is -This should handle reroutes smoothly - if there are no switches between the last communication, point the arrow to the track it will come in on. If the train *could* switch back to normal, have a -- where the arrow is while the arriving track is unknown. Once passing the last switch, then show the arrow. |
