The 21st Century Train Spotter

Due to the ever increasing speed of the domestic train system, some would say miraculously, the train spotter has to evolve. Reactions have to increase, eyesight to sharpen, stamina and physiology to adapt to cope with long periods of inactivity, interspersed with sudden, explosive & vigorous activity. An amalgamation of the hibernators dormancy & the stealth hunters bursts of hard edged, razor sharp reflexes. Kind of like and sleepy & neurotic obese panther.
