Radio Controlled Versions
Two types of radio remote control have been utilised in order to make better use of these locomotives.
Initially locomotives were equipped with radio equipment which allowed the Bergmeister (or Rückenmeister) (The yard hump controller) to control the locomotive. A driver still occupied the locomotive for safety reaons, and to control the locomotive. This method was used in large computer controlled marshalling yards such as Mannheim marshalling yard (German:Mannheim rbf), Seelze, Maschen, Munich, Kornwestheim Rbf and Nuremberg.
Since Nuremberg Rbf has a downward gradient of the track (see Gravity Yard for an explanation), the locomotives are coupled with 6 axle flat wagon loaded with concrete weights that have been converted to brake vans so that it is possible to stop trains of up to 2000 tons in weight.

Famous quotes containing the words radio, controlled and/or versions:
“Denouement to denouement, he took a personal pride in the
certain, certain way he lived his own, private life,
but nevertheless, they shut off his gas; nevertheless,
the bank foreclosed; nevertheless, the landlord called;
nevertheless, the radio broke,
And twelve o’clock arrived just once too often,”
—Kenneth Fearing (1902–1961)
