Davis Street Junction was a small on story building; it housed a 20 lever mechanical interlocking machine. Davis Street was a Missouri Pacific interlocking. It also served as a train order office and the operators were also in charge of some of the road crossing flashers. To operate the crossings there was a toggle switch located about the telegraph desk. By 1964 the interlocking was remotely controlled from Grand Avenue Tower which only lasted for a few years when a train derailment destroyed the interlocking. At that time the track was rearranged and a spring switch was installed. The small one story building still stood but did not control the interlocking; the building lasted into the late 1980's when it was tore down.
