ČD Class 843

The ČD Class 843 is a four-axle diesel multiple unit which was manufactured by Škoda Vagonka. They have been the operator since the beginning of České dráhy for main lines in the Czech Republic, and is the successor to ČD Class 842.
==Appearance==
This train is completely based on its predecessor along with its interior layout. There is a space for a wheelchair, 2 elevated platforms located in the luggage compartment followed by an announcement screen. They are divided into 2 passenger sections, which were separated by a boarding area. Behind the larger part is the second boarding area and luggage compartment. Air-conditioned rooms for the driver are located at both ends along with 2 passable doors at the front. Power transmission is AC/DC. The train is controlled by a central computer.
The train is also equipped with an automatic disc brake and a dynamic brake, effective even at low speeds. Naturally cooled resistors are located on the roof.
==Functions==
They have preferred electric power transmission for higher-performance units. Therefore, the delivery of its older predecessor with hydromechanical transmission was considered an emergency solution, along with the modification of its mechanical part from their predecessor thus created these in the first half of the 1990s.
A prototype of this (843.001) was manufactured in 1995, and another 30 were delivered to České dráhy over the next 2 years. They bought Class 043 passenger cars and Class 943 control trailers that can be coupled with other cars.
In 1998, they were taken out of service because of wheel problems, which was solved a year later by replacing them with new ones with higher strength.
In 2020, they were all deployed in Olomouc and Liberec. In both locations, they provide connections for the categories of all starting services. In 2021, so far 8 (1 of them lent in Liberec) cars relocated from Liberec to Trutnov.
==Trivia==
*This train was operated as a fast train between 3 routes like Praha - Karlovy Vary, Pardubice - Liberec, and Liberec - Ústí nad Labem.
*So far, this is the only diesel trainset that was unstoppable while passed a several amount of stops to Harrachov twice. Although no one were injured.
*This train was once operated with a Class 954 control trailer as a replacement for Class 943 from 2008 until 2014. This possibly could refer to how Class 842 and Class 854 operated too, or they were just test operations.
