The RMC was built to give passengers an even better ride than the standard version.

Its design was based on the original 1957 prototype, CRL4 (later RMC4).

Apart from the special livery, this version is distinguished externally by twin headlamps and electrically operated platform doors. Inside there are other changes with more comfortable and wider spaced seats, and luggage racks.

On the mechanical side, the main differences are the rear air suspension system, a higher rear axle ratio (4.7:1 instead of the usual 5.22:1) to permit higher speed running, and a fuel tank capacity increased from 29 to 41 gallons to allow for the longer route lengths.
