Compare R44 and R46

Recommended Posts

Its probably been described before but can someone tell this newbie the spotting differences between them?

I am used to them on the F line. I recently saw one on the A that had glass or lexan panels around the doorways. Was that a R44? Whatever, it made the car look relatively plush, almost like a LIRR M1. Too bad it no longer had that blue stripe down its side.

The R44s have a matte carbon steel "stripe" along the side of the body. The R46s have a uniform stainless steel appearance. Cars with the lexan panels are R44s.

Thanks for that. I guess that matte finish made it easier to apply the blue paint. So does that mean the R46 never had the blue stripes?

R46s did have blue stripes in the late seventies (see here); I don't know why R44s had the strip of carbon steel however.

Thanks for that, too. It sure was a sharpe looking scheme. I guess MTA abandoned it to save a few bucks. Too bad.

Besides the wind screens by the side doors...R44 cab door is also MUCH smaller than the R46 cab door. R44 is Westinghouse propulsion, R46 is GE propulsion.

the most obvious difference:

 

the 44's have glass between the sideways chairs and doors

the 46's do not

The main differences are in the Braking System. The R44 has WABCO , which lets out a air sound like a fart. The R46 has SMEE which takes longer to let air out then the R44.

The R44 has the better suspension. The R46 have a ride closer to that of an R32.

 

Not true. The R46 has the smoothest ride in the system. The R44 rocks from side to side.

 

Ding ding ding! Round one...FIGHT!

 

Don't turn this into another car argument. :(

I have to agree with the smooth ride...it really "Rides Like A Pullman"!:(

Its very obvious when you hear the 'ghostly' sound of a R46 accelerating, and the extremely distinct sound of a R46 releasing its brakes.

 

R46's are one of my favorites, from what I've seen, the R46 is the fastest of the 75 footers

Note, R46s also had glass in their partitions, it was removed in the GOH. The R46 and R44 differ in their armrest by the transverse seats. The R44 is completely enclosed where the R46 is open on the top. The R46 has splits, lines on it's walls between the transverse seats and the doors where the R44 does not.

 

Regarding ride, the R46 had different trucks when new with shock absorbers. They were replaced with harder riding trucks. Some R46s have bumpier rides than they should, but nothing IMO like an R32. I think both the R44 and R46 are quiet trains and are very pleasant to ride aboard.

Both R44 and R46 are presently SMEE. SMEE refers to the braking schedule, WABCO is just the manufacturer of the system.

It's WABCO.

 

The R44 controller is Westcode. WABCO is the braking equipment.

brake pressure is different (owing to incompatability) with R46 being higher, controller is different (R44-WH, R46-GE) with obviousness.

Think you got mixed up...R44 brake pipe pressure is the one that's higher.

Does anyone have a photo showing these spotting differences for comparison?

The R46 cab door slides like an R32 storm door, while the R44 opens like a regular door.

 

Personally, I like the R46 better.

The R46's run a lot smoother than the R44's. You'll notice that on the (A) line.

 

All the R46s on the A run smoother for the time being b/c they just got an SMS. If you ride those on the V, they are bumpy even at 10 mph.
