Uniform Uniform of a railway engineer, 1860

Rules for wearing the uniform were prescribed by orders and the calendar of ceremonial days. These included religious holidays and days honouring members of the imperial family.

The following uniform was prescribed for engineers of the Institute of the Corps of Railway Engineers and construction schools:

— A half-caftan of dark green cloth, double-breasted and fastened with six buttons, bearing an anchor-and-axe emblem. These symbols of water and land transport routes were used in the emblem of treasury-owned and later state railways. In 1932, an adjustable wrench and a hammer were introduced into the emblem; they are still used today. The rounded collar was made of black velvet. The cuffs had no flaps and were made of black velvet. The collar and cuffs were decorated with embroidery. Light green piping ran along the collar, cuffs, edges of the half-caftan and pocket flaps. The lining was black.

— An undress half-caftan of the same cloth and cut as the half-caftan, but without embroidery.

— Trousers of dark green cloth, with light green piping along the outer seam.

— A sash without tassels.

— For officers, a shoulder belt worn over the half-caftan, made of black polished leather.

— The swords of officers of the Institute of Railway Engineers and the construction school were replaced with infantry-pattern sabres with leather scabbards and a belt of black patent leather.

— A cloak of dark grey cloth, double-breasted and fastened with six buttons. The small turn-down collar could be raised and fastened closely with a loop and button. The cloak had no piping; it was introduced only in 1858.
