This may explain it:



Well, I guess internal combustion is ok up there, the incline cog railway to the summit uses diesels, and external combustion engines are ok, because they use steam engines, too. They go up to a summit development dating from the first half of the 1800's, and the present summit building looks like a stainless steel phallus lying on it's side with a train track entering the business end.

In any case, it's in Wales, and as a carrier of Welsh blood, I can tell you we are all somewhat daft. You drive up the thing because it's there to be driven up. If you can, you will. Just because we used to disembowel Angles up there at the vernal equinox so the crops would grow in the flinty soil doesn't mean you shouldn't drive up there. Damn English and their rules...

Don't expect our brother Reuben (who has been mostly silent lately) to explain. The Welsh don't understand the Welsh, must less do Englishmen...
