I would have thought that it ought to be mandatory in the tunnel operating rules that there are Thunderbird locos at both ends.
After all they made enough fuss about the Eurostars being spittableel and all the self closing fire doors
Better still might be a tunnel rescue train as on the DB» high speed lines, an adapted car carrier with bench seats, or a train of double deck RE▸ coaches, to which passengers could transfer across to the road tunnel.They could be pre equiped with bottled water and dry longlasting sancks.
Is there still one at Newport for the Seven tunnel?
Given the crossovers within the tunnel it ought to be possible to set target to get a loco attached and the train moving or the rescue train positioned.
I would say 60 minutes but that might be ambitious but no more than 90 minutes.
Otherwise as others have said it ought to be possible to get food and water to the stranded passengers via the road tunnel within 90 minutes as well.
There is definately some kind of yellow rescue
DMU▸ parked between the Severn Tunnel and Severn Tunnel Junction. I understand that Newport fire station has a road/rail vehicle on its premises that could be used in the tunnel.
It puzzles me why one of the trains was towed all the way to london using one of Eurotunnels slow speed desel shunters. Even if there not dedictaed thunderbirds, there must have been more suitable electric frieght traction sitting in yards near the tunnel portals. Or is there a coupling compatibility problem at work here?
