Märklin H0 Big Boy Bedienungsanleitung Seite 10

The extremely large locomotive places particular demands
on your model railway system. Before operating for the first
time, please check the following points in order to avoid
damage to the locomotive or your system:
• The usable minimum radius is 360 mm. However, we
recommend that you select greater radii if at all possible
(> 500 mm).
• The clearance profile of the locomotive is wider and
higher than the dimensions specified for European
model railways. Overhead cable masts and signals must
therefore be mounted as far away from the centre of the
rails as possible. Please pay attention to the signal drives,
operating levers or lanterns of the points drives which
might come into contact, depending on the installation
position. You must also take care with the tunnel entran-
ces, bridge handrails and platforms in the vicinity of the
bends in the sections.
• Points should be crossed at the appropriate speed. This
is particularly important for points with smaller radii (up
to 437.5 mm) and for curved sets of points.
• The locomotive has been designed primarily for use with
Märklin C-rails and K-rails. Contact faults may occur in
the event of very slow travel on certain M-rails (curved
points, three-way points).
• Crossings to inclines or gradients and transfer rails (K-rail
to C-rail or M-rail) should not be located directly at the
start of a bend. If necessary, move the transfer point one
rail length further away.
We recommend a careful test run with a second person for
assistance.
