Posted by Newkirk Images on Wed Oct 21 20:49:25 2009, in response to R44 / R46 Question, posted by arnine on Wed Oct 21 19:51:11 2009. I am curious about how come the R44 has a grey stripe versus stainless steel like the R46, plus how come they took off the blue stripes?Because the metal band on the R-44 is carbon steel where as on the R-46 it is stainless steel. It may have been decided that enamel paint would adhere better to a steel surface than a stainless steel surface. I believe there is a special primer needed for paint to adhere to stainless steel as well as galvanized steel. Ever see peeling paint on those galvanized steel windscreens on the "el" platforms ? Surfaces were not primed, just painted. The decision to not return blue stripes to rolling stock after GOH probably centered on making a full stainless steel fleet with no body paint to maintain.
