once again, the great Mr. Keller beats me to the quick!I believe the Tichey scheme was an attempt to de-Pennsy the LIRR. Not lasting very long and I belive was gone by 1955. It was used on as delivered first wave of F-M units and on some RS1. The paint was changed when Tom Goodfellow arrived and then it was Orange ends with Grey carbodies, chainged in 1964 with the arrival of the Centuries. Some of the P and MP series cars recieved the Tichey paint, being light Gray with silver roofs.

LIRR 467 in Tichey.

LIRR 211. Note large fuel tank.
First of the L2s and the only C420s built with the Hi-Ad trucks. MTA paint scheme.
By the way, How many RS3s had the as delivered black cab roof?
I hope this helps a little.
