Surprisingly enough the Eurotunnel's conventional freight services have thus far represented the primary threat to life and limb for Eurostar passengers. The passenger trains themselves are modern, fast, safe, and reliable. Unfortunately the freight services have been far less so. Personally I would prefer that the tunnel regulators focus on preventing unnecessary disasters by clamping down on sloppy shippers and lazy lorry operators/maintainers rather than focusing on restricting passenger rail operations in an effort to survive avoidable disasters.
