 Let's see some of Oliver's commentary

 Irrelevant? How so? What locking conditions exist at the points,
crossovers etc you have included or neglected to number or mention?

  Allegedly? You mean you DON'T KNOW????

  Are you willing to go before a court of inquiry and state either that
you know that a train has passed a signal at stop or are you
speculating upon an incident that has caused a substantial loss of life?

  Making no assumptions? You have already alleged that the Thames train
  has passed a signal at stop.

  The reason I wish people would refrain from making commenting or
making 'snap' judgements on what they believe to be facts.

 How many people would you like to have died Eddie?
  10??
  20??
  30??
  40??

  Are you keeping a running total?

  To a lot of people concerned with the safety of rail passengers,
 an accident likethe one at Paddington is not a joke, nor a topic of
 idle conversation.

 People have DIED Eddie.
