No they have the over riding shoes only.

Thanks!

Any updates?

Still testing.

6 months + on testing. The cars will be obsolete at this point by the time they are put in service.
Either admit Kawasaki screwed up building them or publish a schedule of what's going on.

they are not going into service until sufficient cars are available.
as for testing it is FRA who demands xxx amount of trouble free hours of operation , any fault event resets clock to zero.

Until the cars are sent back to Kawasaki in Nebraska or Japan, no one has screwed up (yet).

No one is obligated to publish a "schedule" here. That is not public information. They will test as long as they have to make sure everything is the way they want it before mass production. If the cars were released with issues aim sure you'd be one of the first to criticize.

Be patient.

Fifty years ago, the brand new M-1's were put into service without sufficient testing and de-bugging and very quickly developed propulsion problems causing large numbers of them to be taken out-of-service for repairs. This was the infamous summer of 1970 where some old MP-54's had already been retired and the remaining ones were barely functional. That entire summer roughly six rush-hour trains were cancelled every morning and evening rush hour due to shortage of trains.

So I guess they don't want to repeat that kind of debacle ever again.

That and standards are different today than they were then.

Back in October LIRR twitter said they are scheduled to enter service May 2019.

What is the minimum amount of cars(pairs) needed to begin in service use of the M-9's??

You could see as few as three pairs introduced into revenue service, as a six car train on some runs. If there's an issue with one car however, they won't run just four cars.

What the plan is however, I don't know.

Are they compatible with M7s?

officially no for service, they can be coupled for equipment moves.
