Fig. 3
Every LGB overhead traction vehicle is
fitted with a switch for selecting the type of
traction: "Overhead or Rail
traction".
The switch isset to rail traction before leaving the
factory.
When the switch is changed to overhead
traction, then the circuit is broken to one set of
wheels and at the same time, is connected to the
pantograph.
The

the vehicle to be parked, (dead).

Single train operation
Electric locomotives are operated without
overhead lines, in exactly the same way as
"normal"
diesel or steam locomotives,
of wheel pick-ups from the two
tracks.
Fig.
1 To enable an electric locomotive to be
operated from overhead lines through the raised
pantograph, three points must be observed:
1.
The overhead catenary system should be
connected by means of the Connecting Mast
6001 (or an Overhead Lines Suspension 6101)
through the red lead to the positive connection of
the
transformer,
(1).
One track rail is connected by means of the blue
lead to the negative connection,
(2).
2. The operating selection switch should be
switched to the mast symbol. Raise pantograph.
3.
Place the locomotive onto the tracks
i.
e.
the electric locomotive should be placed onto
the tracks with the non-friction tyred wheel side to
the live
rail.
For locomotives wh ich have no friction tyres
(2030,2033)
the negative (ground) side is
marked with a "red
spot".
For LGB Technicians
Which rail is the positive?: The positive rail is
always the left-hand one when looking in the

direction
travel. In our circuit plans, the red lead
is the positive, i. e. all vehicles travel, as
the right. Controller knob turned to the
positive pole is connected to the transformer
connection 1.
Two train operation
The overhead lines become especially
interesting when a second locomotive is to be
driven on the same section of track (Multi-train
operation).
Forthis system, a second controller or
electronic controller is
necessary.
Fig.4
The connections to the tracks are normal.
The only point to be
observed,
is that one rail
should be supplied from both negative
connections
(2). This rail is called the common
return rail. The truly overhead operated
locomotive must be placed onto the tracks with
the non-friction tyred wheel side to the live rail. If
two locomotives are to be operated on the same
tracks,
the operating selection switch of only one
locomotive must be switched over to mast, the
second locomotive operating selection switch
remains on "track
operation",
this locomotive can
be placed onto the tracks ad
lib.
Both locomotives
can now be independently
operated on the same
tracks. They can also be shunted and driven at
different
speeds and
directions.
