Berney arms: I take your point about Heuston being better able to redeploy units when there is a failure. What would be interesting would be to compare the failure rates of Mk4 versus DD sets, say failures per 100 scheduled departures. They are after all performing much the same function, even though the journey performed by a Mk4 is about 50% longer than that of a DD.
