the above seems to be a fair report on the situation. I initially heard the story via BBC news and the local paper which takes the line of "local hero sacked for preventing train crash". It took reading this thread to find that the incident took place at the Pier station, without that piece of information one would assume the incident took place at the Town station, which is where he worked.
It would be interesting to see the CCTV footage of where the trolley actually was. The line ends in a sand drag with buffer stop, which is where passenger access is. I am inclined to think most likely whever dumped the trolley did not walk the lenght of the platform, but took the easy option of pushing it straight off the platform edge in the vicinity of the buffer stop, and the incident was not just concerning the trolley, but the litter picking as well.
Electricity can arc, so you don't have to touch the live rail to get a shock. Sometimes in damp weather, passengers in trolleybuses which used a similar voltage would recieve shocks, the offending buses would have to be taken out of service and dried out.
"Train crash" conjures up images of derailment, telescoped coaches, injuries and so on, but it seems that the worst scenario would be a low speed derailment, maybe a few passengers waiting to get out falling to the floor. Don't underestimate the cutting and crushing power of the wheels which is why being on railway tracks is so dangerous. One of the most dangerous places in my raiway career were the sidings where wagons and coaches might be left with only the vacuum brake holding the vehicle. The vacuum leaks off and the wagon or coach goes walkabouts silently and will cut off an arm or leg of someone in the way. Probably at low speed the trolley would simply be crushed.
Again, a danger signal could have been given to the driver of the train, stop the train short of the obstruction and get the trolley removed by those qualified to do so
SWT have had him in their sights because he has not heeded prior warnings about misconduct . You can't have two captains on the same ship, reminds me during my time in the Post Office it was "the union says this, the union says that." But your contract of employment is not with the union, neither does the union pay your wages. Presumably SWT have gone through the oral and then written warnings procedure because I thought that they would have had to show that they had tried to work things out unless gross misconduct such as being under the influence of drink or drugs had occured
Sadly, for all his enthusiasm, he has seen unable to grasp that he is a crewmember not the captain of good ship Lymington Branch
