I don't know if it got slower with the R68s. Probably because they are heavier. When the B had the R40s a few years ago those felt really fast.

Yeah I read somewhere that R68's weigh 90,000 lbs while R40's weigh a mere 56,000 lbs. But idk how accurate that information is

Exaclty! Just do it MTA! Sheesh! Its been this way on the J/Z for years. The skip-stop between B'way Junction and Myrtle is okay, but an express between these stations would be the best thing that ever happened to this line since the EXTREME overdue arrival of the R160's last year.

R40's weighed 72,433 lbs.(33,762 kg)

An R68 (Even # Car) is 92,720 LBS Total with motors at 74 Feet 8 and 1/2 inch long over anticlimbers. The Trucks weigh (#1 End) 18,420lbs and (#2 end) 18,150lbs. Though the R40 trucks are heavier around 19,000 lbs with a slight difference between ends.

You have to remember an R68 has less motors (two less cars)then an R40 but more horsepower at 115HP compared to 100HP. 2000hp R40 to 1840HP, throw in the added weight and different gear ratio you get the R68 being called a Hippo when accelerating.

All bets are off when both types reach balancing speed.
They will move just as fast as each other.

Currently the line that will get you from Bway junction to Manhattan the fastest is the J/Z, even when the J is all local its still faster then the L, the only problem is that it doesnt go mid-town. Z train via Bway Junction-Marcy Av would attract more riders the only problem is that it doesnt go mid-town, SAS could solve this problem but that line is coming for decades.



But what does it look like the R68's are slower than the 60 footers such as the R160?

ok, maybe these are bad examples cause they both look slow.

For those who want to see a real express train, this is how an express train is suppose to run

Yeah if only the J/Z ran to midtown to take some stress off the E. And yeah I believe that the J is faster than the L while local since the L has soooo many local stops lol

As for the last one, gotta get a pic of a (2) entering 50th street southbound, lol.

Both R40 and R160 cars are faster than R68s. R68s feel more heavier than other cars.

By now, most people know my position on the F operating via 63rd. I don't need the aggravation of saying why this is a bad idea. I got in a lot of trouble at NYCTF for doing so. The fact of the matter is that like it or not, the V is here to stay.

Yep, stay for the stupidest routing: 71-Continental to Metro Av

Other than a railfan, who's going to ride the line end to end? The Q38 would be more direct. Also the point is not to ride the line end to end, but to get the most use out of the line. I mean do you ride the D from 205th all the way to Coney Island?
The destination most people are headed to is Manhattan. This V will now take people directly up to midtown than when the M just duplicated J service going to Lower Manahttan.

Just for the record, at another webside, www.Subchat.Com, they have been arguing about the M-V combination route for the past 3 weeks, up to a few hundred messages on their thoughts about this idea.

With change there is the oppurtunity to try something different.

It's usually one person vs. the rest of everyone. It's a non-issue other than that one person losing a one seat ride from 2nd Av. The V, as is, is a waste since it empties out by W4th St. At least if it goes to that area of Brooklyn, riders will no longer need to transfer to the F at Essex.
