I was present at the polmont disaster, was a witness/helper/bystander, take your pick, its seriously not nice ! Farmers fences became a huge issue thereafter, pretty much in the same way that road bridges became reinforced and rebuilt after that guy fell asleep at the wheel of a landrover and trailer and crashed through a bridge wall onto the rails and was hit by train, carnage ensued.Polmont issue was a small cow, but train frontage design was changed almost instantly, as far as i can recall it was a DMU train,not even particularly fast. Polmont has unfortunately not only this disaster with its name, few years earlier a friend of ours was killed cause she got her foot caught in the rails when taking a short cut,a few years later, several P WAY guys, ( track maintenance ) were killed due to a fairly simple error, the whole train / men interface was replaced after that with many more observers now needed . I think !Trains are big and very unforgiving,take a walk around Boness railway museum and get up and close with the "sore" bits of these things and youll never play on the rails !
