The so-called "switch problem"?

[Buddy]

Yesterday around 1230p, I was on a uptown train. After leaving 7Av/53St, it stopped at the 59St/Columbus Station, but turned out to be on the local track. The conductor announced that "this is a express train, the next stop will be 125th." After leaving 59St, the train was switched again to the express track.

 

How can this happen? Was it caused by a switch problem before entering the 59St?

 

PS: There were workers walking in the uptown tunnel between 86st and 96st stations.

It could have been many reasons in my opionion

 

A. Tower Messed up on the switch

 

B. I see A trains on the local tracks a lot then switch over to the express tracks because there is a train at 59th st

 

C. Could have been track work.

 

I'm not exactly sure

Another logical explanation could be that the tower screwed up and thought the was a (, and switched it before it got sent up the local. That actually did happen once last year with a I was on. It seems logical seeing as they share a similar route.

Sometimes Deltas are sent to the local track to get around an early Alpha which is already at 59 Street. After 59 Street, the Delta switches to the express track while the Alpha waits for the Delta to cross in front of it.

Sometimes they screw up and make it even worse.
