Britzka

A britzka or britschka (with numerous spelling variations[a]) is a type of horse-drawn carriage.

What was originally an open wagon in Poland and Eastern Europe, became a passenger vehicle in Austria and was exported to Western Europe where it became popular as a travelling carriage.

There was an elevated seat for the driver in front and a rear platform with a rumble seat for servants[1][2][3] The term is a variant of the Polish term bryczka, a "little cart", from bryka, "cart", possibly coming into English via several ways, including German Britschka and Russian brichka (бричка).

The Great Western Railway engineer Isambard Kingdom Brunel used a black britzka as a mobile office whilst surveying the route of the railway.

Nicknamed 'the flying hearse', it carried a drawing board, outline plans, engineering instruments, his favorite cigars, and a pull-out bed.
