With the recent Lambasting of MTA/LIRR by Newsday fresh in my mind; can anyone give us a current count on how many M9's are on the property and how many are now in revenue service?

Thanks!

And what their real life breakdown rate is versus what LIRR may report?

Photobug, give it a rest...........

Lirr trains have a high breakdown rate. I am wondering how M9s do. Separate issue from comfort but important.

Check the monthly MTA board reports - MDBF might be in there. NYCT does have a monthly breakdown
by car model class.

I would expect the newest fleet to fare better than the DM/DE.

From https://new.mta.info/document/79326 (p73), LIRR M-9s have a 12-month rolling averaged MDBF of roughly 250,000 miles.

But that's per car, not per train. By assuming an average LIRR MU has a consist of ten cars, it translates to 25,000 miles per failure per train, or 40,000 kms per failure per train - even lower than some European or Asian high-speed MUs. And we know that high-speed MUs are inherently unreliable than transit/regional ones...

The thing about the Newsday piece that made the least sense was blaming LIRR's accepting cars with flaws for the delays in receiving cars - seems backwards. If they'd held the line on defects, there be fewer cars in service.

Reading about Kawasaki's performance at WMATA, LIRR and MNR tells me they may be the problem.

Dead thread for a bit. Here’s our newest update. At the LIRR board meeting, it is stated that most issues with the M9s these past months along with the investigation have been resolved and President Rinaldi is very pleased with the beyond expected performance of the current cars. We accepted two more married pairs for the month of march for a standing total of 126. Probably more by now. 9140s are working the test rosters daily as other cars get worked on in arch street and hillside. Rolling average MDBF was just over 232,000 with three failures as the bugs continue to be worked out. We are still on track for the order to be completed by the end of the year according to CPOC. More information should be available during next months rolling stock presentation.
Overall, it seems like we are headed in the right direction again after a few months of delays and hard work.

Thanks for the update!

Ditto! Nice to hear good news on rolling stock.

9155-9156 entered service earlier this week making it the first pair to be accepted for passenger runs in four months. Most test trains are consisting of 9170s now a days and most 9180s have made it through to arch street. The last few pairs await at the Yonkers staging area. More updates should follow by the end of the week when CPOC releases the rolling stock presentation

Thanks for the update Jake Rothman.
Maybe with all these incoming M-9's maybe the LIRR should remove some M-7s from service and replace the sun damaged glazing .
The M-7s are really showing their age.

BM: Yes-The original M7 cars are now 20 years old as of now - numbers lower than 7100 to be exact...
The timing for a mid-life overhaul may be approaching for a lifespan of 35-40 years...

The M9 MU cars have become the prime LIRR "second fleet" over the 80-100 M3 cars remaining...
Again the plan is to bring the M3 cars back to use when ESA to GCT-M opens...MACTRAXX
