C501 is the only loco so far to recieve a nose logo and have the front
window surrounds painted black. See NSW Rly Digest June 97 page 4. C502
only received the nose logo but not the window treatment. C509 has a
grey square and black around the windows but no logo on the nose. Most
Cs had the side V/LINE logo painted out except C506 507 508 and 503
which has been out of service for some time.
