My first cab ride was in G5s #34 from Floral Park to Oyster Bay.
The Long Island bought several cabooses from the NYO&W, and Walter Matuch's RMT center cupola caboose is similar.
As for Long Island rolling stock, LITTLE and the RMLI each produce a commemorative piece yearly. The Nassau Operating Engineers also produce Long Island cars.
