Is this the end of the line?
Ooooo..stop it Peter.
If it's not, I suspect the station will be demolished.
Cant see any cucumber buttys.
Sorry....misread title as Buffet!!
That would be the Liverpool Lime st
platt-form.
Train drivers beware if wheels lock Big Bang please report to inspector Big Trouble.
Frank - Liverpool Lime Street trains tend to come in at Platform 6 these days.
OK, many thanks Dave (Oy).
I would like to know what's in that bolted down orange dome in between the buffers.?
I suspect that the Buffers are an Air on Oil type, The compressed air in the tall, Blue coloured reservoir would be used to extend the shock absorbers (Buffers) by pushing down onto the reservoir of Hydraulic Oil in each cylinder. A check or one way valve would stop that from being able to escape back out again under normal conditions. Under the impact of something hitting the and trying to compress the buffers a much higher pressure would be almost instantly achieved and as oil is not compressible a relief valve would be opened and the oil would have a controlled exit path into a Hydraulic reservoir or accumulator in this case the 'orange dome' .Judging by the massive amount of visible bolt heads holding the dome on it is going to be expected to take a huge in-rush of oil, as you would expect if a train were to run into it.
Sounds good to me Kevan.
