McLernon was born in Jersey City, New Jersey. He spent the first thirty years of his career with the Lehigh Valley Railroad. He began with the railroad in 1920 as a messenger and then served as a clerk, yardmaster, freight agent, and finally as the superintendent of all stations. In 1934 he organized and was elected president of the Lehigh Valley Railroad's first local of the Brotherhood of Railway and Steamship Clerks.[1]
New York City
In 1955, McLernon became the general manager of the New York City Transit Authority. During his tenure, McLernon was able to eliminate the system's deficit.[2][3] He also ordered the installation of automatic coin turnstiles in the New York City Subway.[4]
Boston
In May 1960, McLernon was named general manager of the Metropolitan Transit Authority.[2] He was given an 11-year contract and took office on July 1. During his tenure, McLernon battled the MTA's advisory board, the Massachusetts General Court, and the Carmen's Union, which went on strike twice during McLernon's time in office.[5] On August 4, 1964, the MTA was taken over by the newly formed Massachusetts Bay Transportation Authority. McLernon was chosen to manage the new system.[6] On December 30, 1964, the MBTA board of directors elected to terminate McLernon.[7] Director Robert P. Springer criticized McLernon for having "no concept that the job of management is not the job of a dictator", for mismanaging authority personnel, and for having a "vendetta with the Carmen's Union". He stated that the board chose to terminate McLernon after "his own subordinates disagreed with him and came to the board".[8] McLernon in turn criticized the MTA/MBTA board for not giving him a "free hand to run the system", which prevented him from addressing the major problems besetting the MTA/MBTA. He also criticized the MBTA employees for being loyal to the Carmen's Union and not to "the organization that pays them".[9]
