First of all, Triumph is the name I was trying to remember. Some great material in there.
Just west of Journal Square, at "WALDO" interlocking (it had a 1- or 2-letter call sign in 1910), the H&M through tracks merged with the 2 PRR tracks from Jersey City, and H&M trains used those tracks until the split just east of Manhattan Transfer; PATH trains from World Trade Center to Newark use the same tracks today, except that they now run to Newark Penn Station instead of Park Place, as H&M trains did after the present Newark station was opened. Until the Jersey City station closed (1963?) those tracks were shared by H&M, PRR MP54's, and right until JC closed, PRR's The Broker to Bay Head Jct., pulled by K4's, and later Baldwin sharknoses. I think those tracks were conveyed to the Port Authority of New York and New Jersey when it took over the whole H&M operation because someone had to and there wasn't anybody else willing and able -- sort of like Metra and IC Electric and the Rock Island in Chicago. Each H&M train had its own train number (every 10 minutes!) in the employee timetable, beginning with 0, and any train having an advertised connection with a PRR train to the west or south carried that train's number preceded by 0; in the 1960's the connection for the Broadway was train no. 029, for the Spirit of St. Louis was 031, etc. When cab signals were installed all H&M Newark trains had to have them.
