4 line change in Bronx

Could you explain this in more detail? Would trains skip 135th?

Of all the rebuild scenarios I could imagine, the least disruptive one would probably involve building a parallel trackway for the northbound that dips underneath both of the trackways. The unfortunate result is that it would pretty much necessitate the closure of 145 Street northbound since the trackway has to ramp back up within the footprint of the current 145 Street station. During construction, the would be disrupted—which is better than having the (which serves more stations/passengers) disrupted.

The other option is to sink the southbound trackway underneath the mainline and have it connect to the southbound track from the west after ramping up to 135 Street. This is the more disruptive option as it would cut off service southbound for an extended period of time. I don’t know if it’s possible to build all the requisite structures first and then connect the tunnels to the new structure over a single weekend to minimize service outage.

My only logic question is why a  express in The Bronx. I’m reading a lot of good points, but with the bottlenecks at 149 and 125. Would it be best to leave the  alone in The Bronx in lieu to the connections that are currently available for intra-Bronx and Wash Heights.

Its been established multiple times that the  Express peak express is a horrible idea. They did a pilot years ago and it failed, mainly because you're skipping high ridership stations. The  is already terrible as is, this is just adding fuel to the fire. 

Which  train stop isn't a high ridership one?   Very few of them aren't, such as 138th Street. This is just an example of what happens when no investment in expansion to subway service in the outer boroughs have complicated issues that have been building for years.

Real talk, the Jerome line should just be destroyed and rebuilt again. I feel like the  and  up in the Bronx really needs help. The  just makes lots of stops and the  is so infrequent.

im baffled by this!!!!! :Lots of stops???? Really????

If you want to deal with issues with the , there are the following:

• Slow speeds enter Woodlawn-track layout
• 149th Street Jct.-you could end the  merge
• Variations in operation between T/Os - how they take timers
• Crowding at 59th
• Dwells at Grand Central
• Gap Fillers at Union Square
• Slow speeds in Lower Manhattan-close stop spacing and timers
• Merges at Bowling Green with short-turn s
• Nostrand Junction
• Utica -fumigation-supposedly ended

@RR503 Any others that I am missing?

One thing I would add are those annoying hold to times at 149th GC, and 161st Street. Sometimes it gums up service pretty bad with trains right behind each other at 161

It's not impossible, it just needs to be worked on. You can do a similar setup by adding a switch at Burnside Avenue.

Theres already  switches at burnside!!!!!! The  goes express everyday in the bronx........ you just gotta be lucky to catch that 1 thats going express! LoL...

I think you did a good job identifying all the issues here, speaking as a daily  rider. These are all the issues that the  should definitely be looking into. Let's hope for the best.

There are actually 14 short-turns at Burnside, and they all run express.

Yeah!!!!! This is pretty much accurate. The Gap Fillers are really not a big issue thou........... Unless a T/O Decides he wanna wrap it up and CHOW!!!!!

Nostrand Junction is not a big Issue for the  either because it doesn't have to wait for anybody to get past... Normally the would stop the  and let a  go!.. that way the following  &  goes thru. But sometimes they even screw that up!

Yeah, it's not a big issue. It depends though. But if they let the  be held for the  to go through first, the  behind that  will be held in the tunnel before Franklin. Reverse is true if they held the  to let the  go first, holding up the  in the tunnel before Franklin.

1. The  needs all the trains it can get north of Burnside. (Reverse peak service during school entry and dismissal times is f**king horrendous and that’s *with* all the trains running north of Burnside. Ride a northbound at 7:30am or a southbound  at 3pm on a weekday to see for yourself.)

2. The Lex is at capacity during rush hours. Any improvements to the Jerome line would require  trains to be diverted off WPR and/or Dyre.

3. The  / arrangement works because combined service runs every 4 minutes or better all day, which makes it easier to split service without overburdening local stops. Lack of interlining helps the  as well.

So... possible? Yes. Probable? Ehhh, figure out how to get trains off of the  without negatively impacting service on the Dyre line and get back to me when you have a plan.

It is an issue in that it increases dwell times and slows trains down (the curves)

I know it isn't a major issue in terms of that for the , but the main issue is when delays cascade, resulting from the junction.

Those trains are useless tbh. The express maintains usefulness because after Parkchester they continue to Pelham Bay. The rush hour  trips that run express end at Burnside and head straight to the yard, which benefits nothing except the TA’s bottom line and the train operator who doesn’t have to do 2 reverse moves to clock out.

The conductor has to wait for the next  to Woodlawn, ride as a passenger and clock out from there, so they dont benefit either.

I am well aware of the reason behind these expresses. Based on your experience, do riders heading to Burnside take advantage of them? Do riders get confused and hold up the train?

Well The Thing with the Northbound trains, It those burnside stops are actually not short turns! 80% of those guys doing those runs are Midnight guys who are bringing the train back to the yard. Not a lot of those trains are going back south! same with trains that terminate at Beford Park

And yes.. those T/O create those Gap filler problems because the went past the mark, or the went out too fastened CHOW!

Exactly. The  is an isolated line. The  isn't, because it interacts with the  for most of its run (between the 138th Street-Grand Concourse interlocking and the Nostrand Avenue Junction interlocking), so capacity is limited on the  to 15 tph tops. Also, I especially agree with the reverse peak heavy crowding along Jerome Avenue. I have a close Spanish friend who lives inbetween the  and  in the Bronx and alternates between riding both Jerome Avenue and Grand Concourse lines. That's how I know about the heavy crowding in the reverse peak direction along Jerome Avenue.

Thanks for letting me know about those. What was done before the trains to Burnside started?

The solution to crowding on the  is increasing off-peak and peak frequency on the . As @RR503 has stated, travel times on the  to Midtown are competitive with that of the . That should help a bit.

Peak  frequency (out of the Bronx in the AM and back into the Bronx in the PM) is sadly 6 tph. In addition, peak  frequency (out of the Bronx in the AM and back into the Bronx in the PM) has recently been slightly reduced from 10 tph to 7.5 tph. Let's hope we get the  to look into that.
