The 3 Train being rerouted to anywhere on the 1 Line is a G.O that allows the 1 and 3 Lines to not be so apart, as they part ways at 96th Street heading Van Cortlandt Park/Harlem-bound. This G.O. allows the R62 and R62A models to be present more frequently.

The 2 Train's weekend terminal being at Harlem-148th Street is a rare and exciting G.O because it allows the 2 Line to operate with R62 and R142 models.
