The ultimate Mohawk was a 72-inch drivered L4a/L4b of Lima extraction. Locos 3100-3149 posted a phenominal wartime mileage record: 4.8 million passenger miles and 1 million freight miles in 1944 with monthly highs reaching 24,000 miles per engine. The 3142 is seen here at Weehawken, NJ in 1949, running in West Shore freight service.
