trainfan22 Posted June 7, 2009 Share #26 Posted June 7, 2009 I'm pretty sure the R142A's MDBF is higher than the R142's, making the R142A's more reliable. Nope... R142 MDBF 223161 R142A MDBF 159139 Even the R62's got higher than the 142A.. R62 MDBF 175041 Link to comment Share on other sites More sharing options...
SubwayGuy Posted June 7, 2009 Share #27 Posted June 7, 2009 What a car's propulsion "sounds" like has nothing to do with if it's better or not... The R142's have a higher MDBF therefore they are more reliable. Of course, wasn't always that way...as delivered they had a lot of problems with brake shoe wear because of the radial truck design. However I'm curious how much of the R142 MDBF has to do with E. 180th Yd because they really maintain their equipment very well up there. I even met the Supt. last year and trust me that guy REALLY cares about his trains and takes a lot of pride in his barn's work as well as all those President's awards for MDBF.

Trainmaster5 Posted June 7, 2009 Share #29 Posted June 7, 2009 Any C/R or T/O working the , , or lines on a regular basis knows the answer without looking at the MDBF stats. Most of the posters just based their conclusions on ambient sounds or propulsion or HVAC noises but the car equipment department judges overall reliability and isn't biased toward any one type of equipment.

Trainmaster5 Posted June 7, 2009 Share #31 Posted June 7, 2009 So what is more reliable from your view as a T/O? R142 from what I've seen, and what the people who work the tell me. And they operate both types daily. But remember that an individual's biases must be taken into account and their experience too. Link to comment Share on other sites More sharing options...
R44 5278 Posted June 7, 2009 Share #32 Posted June 7, 2009 The R142's MDBF are higher than the 142A's. I read that the R44's MDBF is higher than the 142A's. Are you sure? The last I checked, the R44s have a fluctuating MDBF in the mid ten thousands while the R142As have a consistent MDBF in the high twenty thousands. no, i think you mean R68/68As. they have the highest MDBF in the entire system at well over 250,000 miles as of 2007. the R44s actually have the worst at around 106,000 miles, and i am not saying that because i hate them. it is true. if you do not believe me, go check http://www.nycsubway.org The R44 MDBF every year is extremely inconsistant. Like I said they fluctuate every year; some years with little to no failure, while other years with the unexplained. I seriously never had one break down and they run as smooth as the R68As. Also, the R68As are the only good trains that Kawasaki had built. Sorry for going off topic. Link to comment Share on other sites More sharing options...
2 Av Posted June 7, 2009 Share #33 Posted June 7, 2009 Dosn't the R142 have the same propulsion as the R160A? Link to comment Share on other sites More sharing options...
6 Lexington Ave Posted June 7, 2009 Author Share #34 Posted June 7, 2009 So, can the R142A be considered unreliable? Are the R143 reliable? Are Kawasaki cars reliable generally? Link to comment Share on other sites More sharing options...
trainfan22 Posted June 7, 2009 Share #35 Posted June 7, 2009 Are you sure? The last I checked, the R44s have a fluctuating MDBF in the mid ten thousands while the R142As have a consistent MDBF in the high twenty thousands. It was posted by an TA worker on another forum that the 44's are predicted to outperform the R142A this year and are outperforming them right now... Dosn't the R142 have the same propulsion as the R160A? Yes, they have the same propulsion... So, can the R142A be considered unreliable? Are the R143 reliable? Are Kawasaki cars reliable generally? The R68A's (Which was built by kwasaki) is the most reliable SMEE's in the history of the NYC subway, as per the MDBF. I don't think any of the R10-R62A have gotten 300,000 MDBF numbers.

Trainmaster5 Posted June 7, 2009 Share #36 Posted June 7, 2009 So, can the R142A be considered unreliable? Are the R143 reliable? Are Kawasaki cars reliable generally? No, the R142A is reliable but there are other car classes that have performed better in the past year or so. There is nothing wrong with Kawasaki cars compared to the others.

Fan Railer Posted June 7, 2009 Share #37 Posted June 7, 2009 Dosn't the R142 have the same propulsion as the R160A? actually, not exactly the same. both are from alstom, but if you listen closely, they sound a little different; the R142 doesn't make as many pitch changes after the starting three, while the R160 makes F sharp, E, D sharp, then alternate between F and D a three times before fading out. for you instrument junkies... while the R142 makes F sharp, E, D sharp, F, and D then fade out (no alternating between F and D) or it could be the annoyingly loud HVAC on the R142 that prevents you from hearing the thing... R160A: http://www.youtube.com/watch?v=xWb9-rA6Du8 R142: toward the end of the video (45 seconds and after) for acceleration Link to comment Share on other sites More sharing options...
Art Vandelay Posted June 7, 2009 Share #38 Posted June 7, 2009 Time between failures is not the only way to measure reliability. MDBF often fluctuates greatly, and so especially when looking at long term trends, it is foolish to look at one month's snapshot of a figure. I would strongly suggest that car availability is a more appropriate measure. The R142A fleet has never had a significant loss in available cars that has required the A division to cut 8(I think-- Memory is a little foggy on exact numbers) trains from the peak schedule. The same cannot be said for the R142. Link to comment Share on other sites More sharing options...
R44 5278 Posted June 8, 2009 Share #39 Posted June 8, 2009 Dosn't the R142 have the same propulsion as the R160A? Yes as well as half of the R160Bs. So, can the R142A be considered unreliable? Are the R143 reliable? Are Kawasaki cars reliable generally? I only like the R68A b/c they are so comfortable and quiet. As for the R142A and the R143, I really hate their siren acceleration. As cool as it sounds outside, riding with it and hearing the siren can sometimes freak me out when I dose off and become extremely annoying. This goes the same with the Siemens Acceleration on the R160B. R143s and R160Bs also idle pretty loudly (my opinion) for a lot of other reasons.

train fanatic 12 Posted November 28, 2015 Share #40 Posted November 28, 2015 Hello. Does anyone in this forum know which type of subway car is more reliable, thus better? The R142 or the R142A? R142A is more reliable and better. The HAVC on R142 is really loud and annoying. R142A has quiet HAVC. R142A has more features on interior while R142 has dull and uninteresting look.

Kamen Rider Posted November 30, 2015 Share #41 Posted November 30, 2015 I know I only just told you this before, but this is an even worse example. This thread is 6 years old. It did not need a new answer, no matter how much you wanted to make it. Link to comment Share on other sites More sharing options...
