General Overhaul Program
From Wikipedia, the free encyclopedia
A General Overhaul Program (GOH) is a procedure of mid-life overhaul on subway car equipment. Recently, the new "State of Good Repair" programs have reduced the need for newer cars to undergo GOH. Some example of the MTA NYCT GOH cars are the R26,R28, R29(all IRT Redbirds except the IND/BMT versions) R40(M),R42, R44(and R44SIR) R46 and others. These older cars were remade during the 1980's and early 90's.
