Function
• Possible operating systems:
6646/6647 Märklin Transformer, Märklin Delta, Märklin
Digital, Märklin Systems.
• Recognition of the mode of operation: automatic.
• Addresses that can be set (Control Unit): 01 – 80.
Address set at the factory: 70
• Mfx technology for the Mobile Station / Central Station.
Name set at the factory: BR 701 033-3
• Headlights change over with the direction of travel.
Digital functions (address of 70)
• Adjustable acceleration (ABV).
• Adjustable Braking delay (ABV).
• Adjustable maximum speed.
• Volume can be changed for the sound effects.
• Setting the locomotive parameters electronically with the
Control Unit, Mobile Station or Central Station.
Digital function with a second address of 71
• Raise, lower, and turn the work platform
• Raise and lower the pantograph
Using this Model for the First Time
• Carefully release the pantograph before placing the car on
the track; the pantograph will come up
• After the voltage has been interrupted (example: by a track
block without current) the Piezo motors must be initialized
again. This occurs for the motors for the work platform
when they are used for the first time. The mechanism for
the pantograph is immediately initialized again every time.
• Before running this car, make sure that the work platform is in the
lower position for height and the middle position for turning. Other-
wise, this car may collide with masts, tunnel portals, signals, etc.
• When the catenary maintenance car has not been used for
a long time or is to be packed away, the pantograph should

be raised and clipped into place by hand.
• The adress 71 of the function decoder is not to be changed.
Advanced Functions (Address 71)
• The mechanism for the platform and the pantograph can
only be activated when the car is stopped.
• The mechanism for the platform is limited to 20 seconds of
movement, provided that you do not make any additional
changes with the control knob. Starting the function again:
Set the speed control knob to zero, turn f1 or f2 off/on.
• When you have reached the end setting, we recommend
that you turn the function off (reduces wear and tear).
• The effectiveness of the Piezo mechanisms can be
influenced by external factors (temperature, humidity, inter-
ruptions in the current); this can be corrected by pressing
button f4 on/off (Address 71).
The prototypical construction of this model requires or
causes the following
• the track on your layout must meet high standards for
precision and construction. While the Märklin C or K Track
meets these standards, M Track might not always meet
them due to greater tolerances caused by years of opera-
tion. For that reason you may have operating problems in
these situations when running the rail bus at extremely slow
speeds or fast speeds through turnouts.
• the coupler pockets are mounted lower than the NEM 362
standard.
• the wheels are mounted deep up in the floor of the rail bus
and are therefore inaccessible for changing traction tires
when the latter becomes necessary. Have the traction tyres
replaced only by an authorised dealer.
