The BLH AS-416 was a diesel-electric locomotive of the road switcher type rated at 1,625 hp (1,212 kW), that rode on three-axle trucks, having an A1A-A1A wheel arrangement.

Used in much the same manner as its four-axle counterpart, the AS-16, though the wheel arrangement spread out the axle load for operation on light rail such as are found on branch lines.

It was introduced in 1950 as a replacement of the DRS-6-4-1500 and remained in BLH's catalog until their cessation of locomotive manufacture in 1956.

Only 25 units were sold to four railroads — all of whom had bought the earlier model. The vast majority (17 of the 25 units) were purchased by the original Norfolk Southern Railway (1942–82), becoming a signature locomotive for the company.
