in PC days triple Headed Gs was almost as common as double headed
Gs in and out of Waverly Yard.
what was rare was single Gs on a freight.
E44/50s Triple headed lot also, but not as much as the Gs.
don't recall too many single E44/50s.
but the Jets and E33s ran single a lot on locals and Express trains,or
maybe Dead Head moves of Express cars ?
