A britzka (also spelled brichka or britska) is a type of horse-drawn carriage. It was a long, spacious carriage with four wheels, with a folding top over the rear seat and a rear-facing front seat. Pulled by two horses, it had a place in front for the driver. It was so constructed as to give space for reclining at night, when used on a journey. Its size made it suitable for use as a 19th century equivalent to a motorhome, as it could be adapted with all manner of conveniences (beds, dressing tables and so on) for the traveller.
The great railway engineer Isambard Kingdom Brunel used a britzka, the 'Flying Coffin', as his travelling office whilst surveying the route of the Great Western Railway, carrying with him his drawing board, outline plans, engineering instruments, fifty of his favourite Lopez cigars and a pull-out bed.
The term is a variant of the Polish term bryczka, a "little cart", from bryka, "cart", possibly coming into English via several ways, including Germanbritschka and Russianbrichka.
