Locomotive bogies for GE Transportation
Special challenge – 3-axle locomotive bogieIn December 2010, Molinari was awarded the
contract for developing a concept for mod-
ular bogies on the basis of the previously engi-
neered bogie for UK.
Following a positive assessment of the con-
cept by GE Transportation, Molinari was also
commissioned with the detailed design.
Molinari was responsible for:
• Detailed assessment of requirements
from European standards
• Configuration of coupling elements
according to the requirements of
dynamic behavior
• Definition of the interface with the
locomotive’s underframe
• Dynamic behavior simulation
• FEM stability calculation
• Detailed design except for wheel sets
and traction motors
• Supply of welded bogie frames
• Static and fatigue limit testing on one
bogie frame
• Support for tests on finished locomotives
Technical data for locomotive • GE Type PH37ACai «PowerHaul»
• Axle sequence: Co’Co‘
• Capacity: 2750 kW
• Max. speed: 120 km/h
• Starting tractive effort: 540 kN
• Weight: 120 - 132 t
• Axle load: 20 - 22 t
Special requirements• Weight savings
• Lower production costs
• Better negotiation of curves
• Easy adaptation to different track
widths and axle distances
• Possible enhancement for
higher speeds
• Compliance with TSI and corre-
sponding standards (EN and UIC)
• Reduction of shear forces through
hydraulic cross coupling

Successful implementation of specificationsThe 3-axle bogie designed by Molinari comply
with all contractual and regulatory require-
ments. The locomotives are approved in the
respective country of destination.
Compliance with the various national regula-
tions and the installation of antennae and
sensor for the various train protection sys-
tems represents a particular challenge. In
addition, maximum shear force is reduced to
less than 60 kN through the installation of a
hydraulic cross coupling.
Molinari Rail delivers the installation-ready
bogie frames as well as the crash compo-
nents to GE.
