Why did the R27/30 stock retire so early?

Recommended Posts

does anybody know why the r27/30 were retired so early? they had an overhaul at coney and got retired about 8 years later but their brothers on the irt r33 lasted until 2003!

was it beacause the st louis car company didn't built them well or they were mechanically almost dead?

I think because they could drag people in the doors. Notice most of them got retired around the same time. They were just not nearly as safe as the stuff we have today.

The sole reason is due to the lack of air conditioners. On one hand, the R27s didn't see a replacement. On the other hand, the R143's sort of replaced the R30's.

 

Oh yea, forgot about no a/c. :eek:

drag people??? as in with the doors holding people that didnt enter the train fully? Ouch...I guess that could be a good reason...along with the AC not being present. more importanly the doors clutching people. imagine if it was a baby or a small child.

The reason the R30/R30A Classes were retired was because of their miseraballyhorrible MDBF(Mean Distance Between Failure for those that do not know). Also because of the fact that when the entire fleet of R30s were taken out of service because of a bracket failure, the (MTA) saw no disturbance in service. They also needed spare parts for the IRT Redbirds. And where else to get the parts? The BMT/IND Redbirds.

The R27/R30/R30A retired and were replaced by the R68/R68A in 1989 expect the R30 GE until 1993.

The R27/R30/R30A retired in 1989 expect for the R30 GE.

 

The GE R30 only lasted until 1993 and retire at the year.

 

The R30 GE rebuild stay until 1993 because the R44/R46 were being rebuilt between 1989 to 1992 so that's the reason why the R30 stayed until 1993 and they retired in 1993 because the R44/R46 GOH was over and there were enough trains to replace them after the R44/R46 GOH was over since the R68/R68A were suppose replace all R27/R30/R30A which it did in 1993.

The part about ac is true. Adding ac would have made the cars too heavy

u know that seems very logical and fitting seeing a though if im mistaken correct me but the R44 did come onto the (A) line thereafter...which would mean it basically took the place of the R30.

Acually the R30 were just sticking till 93 cuz the R44/46 were in GOH, which would make that replace em. R143 mainly just replaced the R40S/M/42s on the Carnarsie (L)

where did those extra 42s and slants go once they were replaced?

I dunno i think they got scrapped. Or possibly got to the (J)(M)(Z) seeing those days they were using them. While the 40s were maybe on the (B)(N) or <Q>

yeah the R44 took the R30's place on the (A) and the R32/R38 took the R30 place on the (C) after the R30s retired when the R44/R46 GOH was over.

 

The R30 were still replaced by the R68/R68A since the R68/R68A were replacing them.

The R27/R30/R30A retired because they were in bad shape/poor condition and it had no AC and they were replaced by the R68/R68A. When the R44/R46 GOH was over in 1992 then the R30 retired in 1993 since the R68/R68A were replacing them.

 

The R30 cloud not have AC then the subway car would be heavy.

oh wow...what made them so heavy...i can guess that the materil or just plain out the way the train was made must have an effect because arent they the same size and shape of an r32 or 38?

Keep in mind that the LAHT Carbon Steel used on those cars weighs a lot more than stainless steel.

ahh i forgot that they dont use the same metal...thanks for the reminder. So they were the same shape...the desity and the weight was more. hmmm but also if the metal was heavier...i wud think that they wud be stronger then stainless stell..but the IRT redbirds strted to rust...can anyone elaborate

Are they heavier than the hippos?

 

I believe so. An individual R-30 weighs about 91,000 lbs. I wonder if R-16s also had the same heaviness problem...

They are just like the R160s nowdays; 60 ft trains with added weight. However, they weren't the heaviest single cars ever built.

One R30 car weighed between 79,000 and 80,000 lbs.an R16 weighs between

84,000 and 86,000 lbs.

Let us not forget that the heaviest 60 foot cars to date are the Stainless Steel R160 fleet.

 

Blows the R30 out of the water by a good 6000 lbs.

 

(They're heavier than the R44s were upon delivery too!)

Oh, I see. So what would have been so difficult with retrofitting the R-27/R-30 with air-conditioning?:confused:
