And what were the last 3rd rail electrics built for the North American market? The New York Central's 1929-vintage P motors?For new-builds, I believe it was the 1930 steeple cabs built for the South Shore line. Although strictly a 1500vDC catenary line, the motors had third rail collectors in case the parent company wanted to shift the motors to the CA&E or CNSM sister lines.
You also have the 1930 order of R-2's for NYC's West Side freight and Detroit River tunnels third rail, later sold to CSS and converted from 600vDC third rail to 1500vDC catenary.
As for rebuilds, you have the 1952 Niagara Junction motors that were built for NJ catenary but rebuilt for third rail use in GCT.
