MIDI OHL
!   How to accept 1600mm pan heads
with 90m spans?
!   Simulations have shown that:
!   Without wind, 1600mm can be
used
!   Particular points in stations to
be studied
!   If wind risk too high: add pole at
span- midpoint

SIMULATION TO STUDY PAN HEAD
COMPATIBILITY WITH OHL GEOMETRY
!  To study the TSI compliance of the OCL designs,
some new functionalities were added to the OSCAR
software
!  Fully flexible multibody model of the pantograph is
now available
!  It allows to study accurately interaction between the
CW and pan heads and contact strips

CONCLUSION 2
• There are many possibilities to accept
pan heads
• The worst case is due to bridges and
tunnels
• In no windy situation 1600mm panhead
can circulate under 1950mm OHL
needing a risk management
• Simulation helps to check compatibility
• French TSI OHLs accept both TSI europanheads
