That should be the Broadway Limited Streamlined K4 Torpedo if I am not mistaken.
Correct. It is the 3768 which was displayed at the 1939/40 Worlds Fair. Streamlined by Raymond Loewy.
S Scale model shown:
While at the Fair the 3768 was painted a bronze color. After returning to service, it was repainted DLGE. The 3768 eventuality lost its streamlining and went to scrap in 1953.
