Traditionally, an airliner is divided into, from the fore to aft, first, business, and economy classes, sometimes referred to as cabins.
Prior to 1949, most railway bureaus (under the direction of the Transport Ministry) had a three-class structure.
In 1949, the first "Limited Express with Reserved Seating" (特快對號車) appeared with the Railway Bureau of Taiwan, and it offered a three-class service, inherited locally from Japanese colonial rule.
This move attracted many more passengers to Midland trains and other railway companies were pressured to follow.
By the end of the 19th century, virtually all British trains consisted of only two classes (still called "first" and "third", both with fully upholstered (and lit and heated) seating arrangements.
Trains in Ireland are primarily operated as standard-class only, with only some of the longest distance services having a higher class, called Premier on IE 22000 Class stock, CityGold on Mark 4 loco-hauled carriages and First Plus on the cross-border Enterprise service.
Premium benefits can be as limited as a reading light and waiter service; but reach to 2+1 recliner seating and enhanced catering options.
It provided just a very low travel comfort, the passengers had to sit on even wooden planks with rudimentary backrests.
Much of the space in the compartments was left empty to allow country folks to carry their goods and livestock inside the carriage.
[1] Executive class trains are the fastest and stop only on a few major stations (first priority).
Economy trains take significantly more time to reach the destination, as they stop on many smaller stations and have to pass all executive and business class traffic going in the same direction (third priority).
Meanwhile, in Jakarta metropolitan area, there's only one class of service available since mid-2013 which is air conditioned and has longitudinal seating;[2] however, a tradition that started in the mid-90s made it customary for commuter trains to be technically classified as executive-class trains.
All members of the Japan Railways Group (JR) offer separated classes of travel, with varying levels of availability on any given train.
A ticket must be purchased in advance, and a special version of the Japan Rail Pass allowing travel in Green Cars is available.
In some stations, Green Cars are located nearer to the staircases and escalators leading to/from the train platform.
[4] Additionally, JR East offers a third category of service, the GranClass, available on its Hayabusa route.
Features of GranClass cars include leather seats that recline to a 45-degree angle,[5] raised footrests, adjustable dining tables and cocktail trays, and personal reading lights.
Full-service meals, both Japanese and Western, are provided by specialized GranClass attendants, who also serve soft drinks and alcoholic beverages.
Because the Hayabusa is a long-distance service to the Tōhoku region, overnight amenities such as slippers, blankets, and eye masks are provided.
Commuter trains in USA and Canada rarely offer multiple classes of service.
