Brightline Trains LLC (formerly All Aboard Florida and Virgin).General Discussion - Passenger Rail: High Speed and Heavy and Light Rail Systems.Amtrak doesn't necessarily respect them in the NEC timetable, but all of the bridges/crossings were redone to start from MP 0 at South Station as of at least 2016, based on the MBTA track chart I have. The change just happened around the same time PTC was introduced.Īctually, the MBTA mileposts on the Dorchester Branch were renumbered to start from Boston a few years ago.
Pan Am has been using mileage prefixes for years for everything not on their standard 'Keag mileage chain. When you have the same dispatcher issue something at MP 15 on two different lines in close proximity it can be confusing.
I don't believe Amtrak uses any mileage prefixes on the NEC.īy the way these were not PTC induced. The exception is the Dorchester Branch, which is in mileage from NYC like the Corridor is.
The prefix of B was to denote the milepost form Boston, yet a large exception remains from that logic. They are a mix of either the Line Prefix, or the PTC induced milepost designation for each line. Trinnau wrote: ↑ Mon 8:34 am nomis wrote: ↑ Mon 5:47 am
