4 line change in Bronx

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.

Yup. The MTA abides by their stupid loading guidelines.

Their response is "Oh. Trains aren't crowded, then let's cut service within "acceptable limits.""

It should be: Oh. Fewer people are riding the train. Why is that? What could be done so more people could ride the train?

Well they could be a regular crew during the Night but the end the trip with a Lay Up!.. That one train probably been on the road all night and its getting put into the yard to be serviced. A lot of Trains rotate!.  Like one of my Trips, i report  to Mosholu Tower, But Instead of going to Mosh Yard , I go to Concourse Yard to get My train, Then i go Straight into Service from the Yard to Kingsbridge. But Ill end my day at Woodlawn! all schedules are different

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?

There's no real confusion, and most get off them at 161 and 167. Some stay on to Burnside and if there's a crazy gap for the next train to Woodlawn, the smart riders head downstairs for the Bx32 (most are going to Fordham and Kingsbridge anyway.)

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.

Doesn't help anyone going to the Upper East Side or downtown (helps with Midtown tho, especially 34th Street.) The and  reverse peak is better by far, but all the schools are by Jerome which is why the gets slammed but not the  and .

The gets slammed in the peak direction. The  serves riders better south of Burnside, but the and combined serves riders better north of Tremont, but only if you have the flexibility to take either line on both ends of your journey.

Holy shit, there are so many other posts to reply to since I started typing.

Without a doubt. Hence we are fighting for increase in service.

It's mainly because it depends on how interested a member is in a particular topic, including me. Agreements as well.

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!

Man those AM jobs that drop out at Burnside are the ish, those are usually the heavy hitter penalty jobs and the WAA is beautiful lol.

Am crews atleast when I worked one of those jobs start up at Woodlawn make a trip down to Utica and on our way back we drop out at Burnside. Midnight crew go from WDL-NLTS and on their last half (2nd trip) from Utica they drop out at Burnside.

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?

- The issues at Union Square are equally bad in both directions. S/b it's gap fillers causing long dwells as you've identified; n/b it's terrible passenger flow. 

- The BG terminal is bad in both directions as well -- s/b you get hit with fumigation delays, n/b with the merge. 

- 3 track from Franklin to Borough Hall is a hornets nest of 1 shot GTs. You note the variability problem, but I think that stretch is worth highlighting independently

- 125 St is chaos -- long dwells, 10mph 1 shot enforced leaving speed nb. It's not constraining given how much of a dumpster fire the core section of Lex is, but it certainly contributes to lengthened peak-hour runtimes.

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!

I've noticed that frequently, a  will get held for a  or  crossing in front, which in turn plugs a  coming downhill into Franklin. No direct crossing interaction, but the cascading effect certainly hurts s.

On the question of  service more generally, I tend to say no. Assuming the proposal are express trips from 149 to Burnside, you first run into the issue of merge delays. Skipping 5 stops will save you 2.5-3.5 minutes, or almost a full  headway...which means you arrive at Burnside at about the same time as your leader. Then what? Somebody is getting a merge delay, or you extend the express segment of the  even further north, reducing its potential catchment and thus the case for express service, etc.

As I see others have noted, there's equally an issue of yard access. M track on Jerome gets a *lot* of use in this capacity. Again, assuming this is just an express as far as Burnside, you'd avoid put ins in the AM around BPB, but the first Burnside drop out arrives at Burnside before 9 AM! You're either going to have to move it to the local (running the risk of fumigation delays), keep the set in service (what I would do), or end express service quite early. Tractable, but again, something to think about. 

There's finally a load balance argument.  would undoubtedly attract riders from the  which we...really don't want to be doing, given Lex loads.

The  is so bad during rushes that a significant number of people ride to Tremont or Fordham and then cross over to the downtown for access to local stops. That's...embarrassing.

On the point of loading guidelines more broadly, they're an objectively terrible way of structuring service. In a networked system, the interactions between lines make things like transfer times and turnover and network load balance equally salient variables even to cost considerations (not that we should be structuring service around costs alone, but to speak the language of the agency...) as is crowding. Routes that have high turnover -- like the  -- should get more service as a reduction in their headway shortens transfers of more high-density trip types, making them more attractive and increasing revenue proportionally more, etc.

I knew I was forgetting something (3 track). @Ben Kabak can attribute to that.

It would be great to get (maybe crowdsource) TPH figures for Non-revenue moves.

The same goes for buses! The last time the agency actually did that for the subways and buses— with LTD stop service and increased express service as the Fare Deal — it worked! What a surprise.

There have Ben times when i was working the 5, Ill leave Franklin only to get held at the junction so a bum as  that entered the station after i left can cross ahead of me! smh!

While the  won't help pull some loads off the  all the way, it will certainly make it alot more attractive to Grand Concourse local stops, especially for Yankee Stadium. I feel like the  to Bedford Park in the PM ends far too early, as during baseball season, trains are slammed to the core. Yet the 's only solution is to have that  Express cross over to local for 161 (after bypassing 155 on the express) before crossing back to express. Horrible.

I think the  could help a lot -- it has cross platform transfers with the  and  into Midtown, after all. Just a question of getting everybody's frequencies to a level at which CPW is attractive.

Eh. If we kept some 32s/cut out some of the ridiculous runtime adds implemented in peak hour schedules, we may have. Foreign systems also have much lower spare factors than do we largely because their car maintainers work overnight rather than during the peak, a practice whose adoption could free up a significant portion of the fleet for service.

That's another form of poor dispatching right there. Exactly what I was telling @Lawrence St in the other thread about DeKalb Junction... Reverse is true when my  pulled out first, and that trashbag  second, the latter goes ahead first...

@Union Tpke, the R211 order should fix the subway's overall fleet expansion, as most of the R42s are now out of service permanently and the R32s' age requiring a higher spare factor.

I agree. What do you think the solution with the schedules? Actually changing schedules to reflect reality would require adjusting times throughout the line, requiring changes to essentially every other line since they are so fragile. 

Have car maintainers ever worked overnight in NYC?

Well aware of the second issue. Some of those expansion cars will go to the  for increased service, some will go to the  for 10-car trains, some for longer   trains, and hopefully some to the  for an extension into Brooklyn. They should keep all 50 R42s and 222 R32s until the R211 order is complete. If anything transfer the R32s to the  and more productively use the R46s. (I know, OPTO, it was a joke)

 I don’t know about all of that, but I have tried it from Mosholu Parkway and it is brutal. It takes forever. I don’t consider it a real option, especially compared to the . For those of us in Riverdale, we don’t have a real East Side subway. The Bx1 takes a while and the  is very slow.  By comparison, I’d rather put up with the numerous transfers necessary from it to reach the East Side or just take an Uber to Metro-North or the shuttle bus, which is much faster.

A crosstown along 125th Street would help with that. Too bad it won't ever happen.

I think that's exactly what should be done, but only after runtimes are stable (ie no more SPEED projects in the pipeline). I also think that the scheduled runtimes should be somewhat more aggressive than they are today so that the incentive to run a tight ship is maximized.

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.
