I know that the New York City to Philadelphia section of the Northeast Corridor has been out for years and they've done the Pennsylvania Railroad GG1 and I think that the Penn Central Arrow I MU would be another wonderful throwback. The Arrow I was used for NYC-Trenton Service on the Corridor from the 1960's to 1980 and were created after the Silverliner II Mu for the Pennsylvania Railroad which later became Penn Central these railcars later became the comet IB for NJ Transit.
