Then, this derailment wouldn't be possible as long as the timers are placed correctly; hence the word "protecting".

1. Which area specifically is impassible? 2. How does running a timer cause a train to derail?

I literally have no freaking clue what you're trying to say here. I'm sorry, but you seem to be violating an NYCTF posting rule: In any case, it's not a question about whether R143s could potentially run on the . It's about whether it's specifically a good idea. For example, R68s could theoretically run on the , but it's hard to see why it would make sense.

But, if there are no cost savings, why bother to put R143s on the in the first place?

It's not about the T/Os; it's about reducing maintenance costs. There's no rule against spreading out cars, but it's better to avoid it when possible.

I've been thinking about this, and since there are so many possibilities that could theoretically work, we have to understand that it's better spread car types over as few yards as possible. Thus, putting R143s on the seems attractive because it would leave ENY yard with only two car types (R160 and R179) and 207 St yard with only one (R143). The question is whether there are enough R179s to displace all of the R143s from ENY, because if there are any R143s left there, there's no point in moving any to 207 St in the first place. The other issue is that if the is supposed to get R179s too, the R179s are no longer isolated to ENY and the cost savings of displacing the R143s are gone.

Well, I would have the express trains switch to the local track after 71 Av and terminate there. That wouldn't interfere with trains running local, although the switching might cause delays to trains. If that's a problem, here's an alternative solution: runs via 53 St runs via 63 St

That's true, but the train alone can't handle the crowds at Lexington/53 St IMO.

via Queens Blvd Local select trains via 63 St IMO you've cut service way more than necessary. Expect severe crowding on trains and all Queens Blvd trains.

Could you please speak English so we can understand anything about what you're trying to say?

I don't know. Have I done a lot of scenarios with them?

NEXT: Due to switch replacement, the area west of Atlantic Av-Barclays Center is impassible. This is a long-term, planned service change. Note: trains can still enter Atlantic Av.

LOL @ the idea that SubChat has less foam than NYCTF...Maybe they have good sources, but when a knowledgeable person brings something up, everybody else goes crazy with foam.

The was having some delays this afternoon...Anyone know what was going on?

I smell the usual SubChat foaming...

That's because it sort of is. Same with a lot of railfans, though...I don't mind that Threxx is really, really interested in trains (I am too), but it's that some people are just looking to prove people wrong over topics that are more trouble than they're worth...

You got the two mixed up. It's the Siemens that cuts out at 5 MPH.

Well, won't the new cars run in the same trainsets as the old ones? If that's the case, then the new motors will have to be compatible with the old ones.

Whoops, I guess it was your plan that I was reading.

You didn't see my rules. In any case, if we're going to account for all trains, I don't think there's anywhere to put the trains if you suspended it... BTW, if anyone's curious about the Manhattan Bridge closure scenario, here's what the MTA's plan was for if they actually did have to close it: http://www.erictb.info/erc.html

How many TPH go to 21 St-Queensbridge? Running all trains through 53 St is too many TPH, so it would need to be a bunch.

Good point. I forgot how many TPH the was. NEXT: the switches between the 63 St tunnel and the Queens Blvd Express tracks are unusable. Rule: you can't cut any trains to only Brooklyn or Brooklyn and Lower Manhattan.

Here's what I'd do: runs in two sections: 71 Av - Whitehall St 95 St - Court St runs local between 14 St-Union Square and Brooklyn Bridge to provide a transfer at Canal St Your idea to suspend the majority of the line isn't good because not only is there nowhere to put those unused trains, but you've also screwed up Manhattan and Queens riders needlessly.
