Can anyone help with the following
1) what pressure do the whistles operate
2) what are the dimensions ( say from a C stock car)
3) what would be the best route to take to buy one, if 1+2 are suitable for one to fit on my 5in gauge steam loco? ( it would be under the tender!!)
Thanks
Ron
Oh had a bit of a bonus on Sunday on the outer reaches of the Met top and tailed 66 on a weedkiller rain, the chiltern class 117? sandite/weedkiller, and then the A stock RAT all running

On 'conventional' Stock, '72/C at main-line air pressure 85lbf/in2.

Obtaining a whistle would be probably best done by contacting TfL and Knights Rail Environmental, who are scrapping the C stock, and asking if you could purchase one.

as Dstock says, they operate at main line pressure, but they also need quite a high flow rate to get them to sound, as I have discovered in the garden! I use a DIY type compressor to charge the main and train lines, and blowing the whistle is the fastest way to discharge the lot....Assuming you will use steam from your loco you may need to modify the whistle by reducing the size of the "hole" or you might rapidly have a static exhibit!

Thanks for the replies, off to knights rail to see if they will play ball.The boiler will be pressed at 100psi so it looks like it should be ok. Only use them for starting off from the 'station'

Perhaps a trackside whistle would be more suitable as they operate on the signal air main at 60psi maximum. I expect they are mostly redundant these days with cabins closed and signal linemen centralised to depots. I can't recall the last time I heard a trackside whistle blown legitimately by a signal operator to call a lineman to the cabin/IMR but it was several years before I retired. Everyone has a mobile phone so the whistle is rather superfluous, I'm not even sure that they are maintained nowadays. Of course I did have occasion to test one or two myself after borrowing the supply fuse to feed more important circuitry in an emergency pending the availability of a replacement fuse and I can recall someone pushing the wrong button on the Acton desk at Earls Ct in the wee small hours and blowing the whistle at Ealing Common, definitely a no-no in the early days of noise abatement and probably a very cardinal sin these days. |

Thanks, i got in contact with Knights and they 'cannot' sell as they only dismantle!!!
It should work as the boiler is pressed at 100 psi.
Now any idea who i contact in Tfl, the site is very vague
Acton Works manager?
Someone with a spanner who works there and will exchange one for 'a drink' ehem ehem. Not that i condone such an action

Whilst they aren't used to summon cable linemen anymore, they are most certainly used to hurry drivers along - Upminster cabin certainly makes use of theirs and the Earls Court one can be heard on rare occasions! |

I was on work experience in Rickmansworth signal box for the day and I remember talking to the signalman about the whistle button, and he told me he uses it to 'wake up' the drivers who are in the platform for too long making them late. First time I heard one too, I think he said it was still maintained too. |

Gosh, two admissions in quick succession about drivers having to be 'woken up' by the dulcet tone of a 'casey jones'. Not quite as effective as waking up the signal lineman when he happens to be standing next to one. I got caught like that at South Harrow one day as I stood outside the IMR locking up, the whistle being immediately adjacent to the door a little above head height! The shock was not too dissimilar to a dentist detecting a bad tooth with his equivalent of a toffee hammer!

I managed to get a good look at one of the C stock whistles on Sat at Edgware Rd.
The are a lot bigger thn i thought esp in the girth depth.
Looks like the possiblility is now a non goer, due to the diameter, length is ok, but it would take up a lot of the coal/water space
Anyway, Thanks for all the input, it certainly got the brain cells working on it for a while
