Question

What subway goes from grand central station to 42nd street or 34th street?

Answer 1

A 10 minute taxi ride is a lot faster or a 20 minute walk

Answer 2

The IRT 42nd Street shuttle service 'S' operates from Grand Central Subway Station to Times Square - 42nd Street.

From there you can then use the BMT Broadway Line platforms to go one stop south to 34th Street - Herald Square, on 'N', 'Q', 'R', or 'W' services.
