The BLH AS-16 was a diesel-electric locomotive rated at 1,625 hp (1,212 kW), that rode on two-axle trucks, having a B-B wheel arrangement. It was the successor to Baldwin's DRS-4-4-1500 model, and remained in production until Baldwin-Lima-Hamilton quit the locomotive manufacturing business in 1956.

Nine railroads bought 127 locomotives, with five railroads having bought the previous model. None have survived into preservation.

Usage

The AS-16 was designed as an all-around useful locomotive, capable of freight or passenger service. The engine had optional benefits such as a steam generator or dynamic brakes. The AAR Type B truck warranted higher speed than its siblings, the AS-416 and AS-616, with their three axle trucks.
