Moscow Central Diameters (MCD) (Russian: Московские центральные диаметры (МЦД), romanized: Moskovskiye tsentralnye diametry (MTsD)) is a system of off-street passenger rail transport lines in the Moscow agglomeration, created at the turn of the Moscow railway. In the media and ad campaigns, the project is also widely called a "ground metro" (City media call it the Moscow Metro), although by definition of characteristics and technical equipment it is not one - the MCD has influence with the metro only by a single fare payment system (but you can also buy a separate ticket).
