Following the numerous breakdowns of 373s in the tunnel a few years back, there was a comprehensive engineering study of what went wrong and recommendations made by an SNCF senior engineer, from memory these included:
In the power cars:
1) remove no-longer used DC equipment to create additional space.
2) Increase air gaps between 25kV conductors & body in the roof area.
3) improve sealing of electrical cabinets,
4) changes to panto mechanism (means of manually raising)?
5) use different outer grill construction in winter
6) also have more Krupps locos with fume filtration available at each end of tunnel.
Anyone know if these recommendations were all implemented or were any discounted as being unfeasible on further analysis?
