FortunFortunately, PATH terminals' platforms are wider than usual..un
daveklepperWith PTC it should be possible to reduce headways on each track to 90 seconds, for a three-minute headway on each route. This will require motorman to drop back one train at terminals, except at the WTC loop tracks, to change ends quickly enough.
You might need at least one 'pool' motorman positioned near the arrival end of the platform to get this to work properly, unless you can arrange a quick way for him to get out of the 'cab', down the length of the train clear of the pack of arriving passengers, and back into the other train in time to attach handles and do necessary testing. (This is essentially what Dave was saying in terms of what the motorman 'dropping one train back' would be doing in the interval.)
The 'plan' would be to use motormen the way PRR used GG1s at the Army-Navy game: you needed just one extra locomotive. Trains would pull in on adjacent tracks, engines first of course. The 'extra' locomotive would couple to the end of one train and pull it away, leaving the G. That locomotive in turn would couple to the end of the next train ... and so on, until you had one light G to return by itself to the engine terminal.
The question is what would happen if one of those Gs were impeded by a crush of passengers boarding that next train ... it might make sense either to have more than one light engine, or to find a way to move the engine on a track that is not blocked by passengers. That is the situation I see for rapidly changing ends on trains dispatched at minimum CTBC/PTC spacing into terminals...
[I remember joking, many years ago when I first learned about the pot-smoking brainstorming session at the MTA that produced the Welfare Island cable car, that a powered zipline would be a nifty solution for this problem of switching the motorman quickly ... tongue in cheek, of course, but still...]
BTW: it would be interesting for many people reading this thread to be reminded why "PTC" is being used on the Hudson Tube lines, which would seem at first glance to be a subway or transit type of operation...
Every four miniutes is for each line. But this means that effectively there is a train every two miniutes on most of the system, except between Journal Square and Newark, where only one service operates. At World Trade Center you have Hoboken and Newark trains. At Journal Square you have JS-33rd trains and Newark - WTCtrains. At Hoboken you have 33rd St. and WTC trains. At 33rd (actully 32nd) St. you have Hoboken and Journal Square trains.

Now PATH is starting to install PTC on the 33rd street route. This route is also overcrowded. By installing PATH "may" be able to run trains closer together. Two possible reasons are as well as others :
1. Install on a lesser use line to correct any bugs.
2. Anticipation that in the unlikely closing of one of Amtrak's North river tunnel bores NYP to NJ that the sudden increase in PATH passengers to the NYP area ( 33rd st vs 34th st ) can somewhat be carried by closer headways ?.

Ah, there he is, staying (very wisely) in the door of that vestibule so he won't be a cat on a hot tin roof.

Here there be cats. LIONS with CAMERAS
blue streak 1Now what happens if one of the north river Amtrak tubes closes unexpectly.
The answer to that is simple. Stay home cause you ain't going to get over there anyway.
LION has LONG suggested that the LINCOLN TUNNEL allow buses only in the AM. (LION wants to keep cars out of the CBD.) Let trucks through for free at night and charge a $50.00 toll in the daytime (outside of the bus only hours).

I get in at the witching hours of the morning. should no problem
Article mentions that PATH is starting to get very over crowded. Noted that trains run every 4 minutes and suggests running every 2 minutes. Read second comment that explains that is not possible due to differnet routes sharing some tracks.
