In short: there is no such thing as steam..
Except there is - the dispute was only about the words for it. Steam is fine as an everyday word for whatever comes off the top of water when it is heated enough. If you want to discuss exactly what's going on with this steam scientifically, you need scientific terminology, in which the water substance can exist in each of the three familiar phases*. What you see in reality will probably be a combination of them, and other things. Customary usage in many technical fields also uses "steam", and in context that isn't a problem - for example if that pipe has steam going up it, and this one has water, that's all you want to say. * At least. As well as plasma (not really a phase of one substance) those pesky physicists do keep inventing new ones. |

'When I use a word,' Humpty Dumpty said, in rather a scornful tone, 'it means just what I choose it to mean — neither more nor less.' 'The question is,' said Alice, 'whether you can make words mean so many different things.'

It makes you wonder where the real problem lies - fire, or stupidly installing alarms?

Perhaps the real problem is in the outdated practise of carrying a fire around with you on a moving platform?  |

Perhaps the real problem is in the outdated practise of carrying a fire around with you on a moving platform? I thought it was contained in the text here: Network Rail said in a statement: "Earlier this evening a charter steam train upon arriving into London Victoria station had set off the pre-alarm on the fire panel.
"Although no fire was discovered and the issue was confirmed as a false alarm, the fire alarm system entered full evacuation mode and the correct process for a full alarm was carried out as per the safety standard. So what is a "pre-alarm"? I guess it means the sensors have a second threshold below the "full fire" one, to give better sensitivity, but allowing the inevitable false alarms to be quickly cancelled. If so, then the system should not have entered full evacuation mode. So it's a software fault, in the broadest sense, or possibly user error (e.g. pressed wrong button). |

A "pre alarm" is usually understood to mean that a smoke or heat detector has reached the alarm threshold, and that staff are alerted in some non public way and go to the area in question to inspect and see if there is a fire.
The person inspecting for fire has some short and pre-set time to send a message "all in order, no fire" If this message is not received and acted upon in time, then the evacuation warning is given.
The pre alarm is also often given in some discreet way to staff in retail units in order that cash and valuables may be secured before an evacuation.
Most fire alarm systems also give the emergency evacuation signal immediately if more than a certain number of detectors are triggered.

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU▸ is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

At larger stations a pre-alarm is often accompanied by coded PA▸ messages that alert station/retail staff so they are prepared should the general alarm sound. The most common PA mentions " Inspector Sands". |

Years ago, an announcement at Bristol airport for "Extension 286 to contact..." was the signal for Special Branch to put the tea down and get running.

If there is a more appropriate thread to post the undermentioned mods please act accordingly.
Alan Peglars, the man who originally saved the Flying Scotsman, last wish was his ashes to be consumed in the firebox of the locomotive.
His last wish was carried out yesterday by his daughter who was on the footplate of the locomotive and placed his ashes on a shovel which she then carefully consigned into the firebox whilst the engine was en route to York.
A truly fitting tribute to Alan.
Thank You Alan.

Yes, we have a lot to thank Alan Pegler for. Even if Flying Scotsman all but bankrupted him. But... the Flying Scotsman
Tut tut.   |
