I have a lot of sympathy for history and heritage and while I have little knowledge of the goodly populace in those parts, with their well-meaning bucolic faces and kindly hearts, I am not displeased to see the bulldozer of 'progress' thwarted occasionally. As far as train operation goes though I would imagine the imperceptible accumulations of wear and tear, due to deceleration and acceleration, and energy required to reaccelerate the mass, would mount up.
