They were built in order to revive TCDD's failing image in the early 1990s, for use on the Capital Express.

TCDD's image was failing greatly in the early 1990s and its Ankara−Istanbul mainline was losing market-share to roads.

People mostly chose buses over rail for travel, because TCDD's fleet of railcars were aging quickly.

During winter times, the steam heater on board the cars always broke down or malfunctioned causing problems.

To make things even worse, a highway was opened between Istanbul and Ankara decreasing travel by rail considerably.

The railways needed to improve travel or they would lose a lot more customers to roads.

TCDD's bad image started to improve almost instantly and the Istanbul–Ankara main line was getting increased travel.

Because of the success of the railcars, TCDD ordered even more of them and soon started to replace their entire fleet with them.

Inside each compartment is a small sink with a mirror, a counter with a minifridge and cabinet as well as an overhead baggage rack.
