: Superliner

Many travelers prefer the comfort of a Superliner because it offers amenities not found in standard railcars.

Examples

For my long trip across the country, I booked a sleeping berth in an Amtrak Superliner train.
This is because the Superliners seat just short of double the coaches on the CZ in '61, and the sleepers of today, if fully booked, sleep 40, whereas the classic 10-6s slept 22.

Morphology

Superliner = liner (semi-transparent) = super + liner

The prefix 'super' suggests something large or superior, but the specific reference to a type of railcar is specialized.

Etymology

Superliner comes from super- meaning 'above' or 'very' and liner as in 'ocean liner' or 'airliner', meaning a regular passenger vehicle. So a Superliner is an 'extra large' liner — the name Amtrak uses for its large, double-decker long-distance train car.
