⁴ᴷ R211 A Train pulling into 42 Street-Port Authority Bus Terminal 

By looking at this video again. The motorman slowed the train down too soon like after only about the first 5 car set of the full length of the train entered the station. Meanwhile the clip of the Brooklyn bound R32 C Train flying down on the express track at 42nd. Also, there were was an R160 C Train that flew down the express track at 42nd Timesquare

The R211As need to do a lot better than that with the speed. They seem faster than the R179s but not fast enough like the R160s
