MIDI OHL

How to accept 1600mm pan headswith 90m spans?

Simulations have shown that:

Without wind, 1600mm can beusedParticular points in stations tobe studied

If wind risk too high: add pole atspan- midpoint

To study the TSI compliance of the OCL designs,some new functionalities were added to the OSCARsoftware

Fully flexible multibody model of the pantograph isnow 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 andtunnels

In no windy situation 1600mm panhead

can circulate under 1950mm OHLneeding a risk management

Simulation helps to check compatibility

French TSI OHLs accept both TSI euro-panheads
