The locomotive pictured on the front of this post card is a Missouri-Kansas-Texas Railroad (see below for details) Baldwin Lima Hamilton AS416 (see below for details) that was eventually repowered by EMD (see below for details). The result is the humpback hybrid seen here at Kansas City in 1972.
All the information below was taken from our good friends at Wikipedia.
The BLH AS-416 was a diesel-electric locomotive of the road switcher type rated at 1,625 hp 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 Baldwin Lima Hamilton'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.
Most of us think of Baldwin Locomotive Works as only “Baldwin”.
The Baldwin Locomotive Works was an American manufacturer of railway locomotives from 1825 to 1951. Originally located in Philadelphia, Pennsylvania, it moved to nearby Eddystone in the early 20th century. The company was for decades the world's largest producer of steam locomotives but struggled to compete when demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation.
EMD has an interesting history, too. Electro-Motive Diesel (abbreviated EMD) is a brand of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. Formerly a division of General Motors, EMD has been owned by Progress Rail since 2010.
The Missouri–Kansas–Texas Railroad (reporting mark MKT) (1870–1988) was a Class I railroad company in the United States, with its last headquarters in Dallas, Texas. Its predecessor was established in 1865 under the name Union Pacific Railroad (UP), Southern Branch, and came to serve an extensive rail network in Texas, Oklahoma, Kansas, and Missouri. In 1988, it merged with the Missouri Pacific Railroad and together they were part of the UP.
Here is the back of the post card. It was published by the mysterious railcards.com out of Alameda, California.
