Can anybody tell me what the lineside klaxons are all about on the run from BPW» (Bristol Parkway - next trains) to Swindon?

Heard them in the cutting after Chipping Sodbury tunnel and then again on the approach to the junction with the GWML▸ (Great Western Main Line) before the approach to Swindon.

K. Thanks for that Super TM‡(resolve). Not come across these before. Are they used to avoid temporary speed restrictions when PW▸ (Permanent Way) gangs are at work? I didn't notice any slowing of the train.

In some places they are permanent fixtures i.e where the line has reverse curves and the like which give inadequate sighting for lookouts.  There are also portable versions which can be set up to protect worksites.  Nothing to do with temporary speed restrictions at all.

Dare I ask what the 'Pee Wee' warning system for lookouts is all about?  Roll Eyes Shocked Grin
Logged
William Huskisson MP▸ (Member of Parliament) was the first person to be killed by a train while crossing the tracks, in 1830.  Many more have died in the same way since then.  Don't take a chance: stop, look, listen.

"Level crossings are safe, unless they are used in an unsafe manner."  Discuss.

Its quite an old system now.  It consists of at the site look out location a box with a klaxon and a telephone hand set, a cable is run out to the advance lookout who holds a telephone hand set.  Both the site and advance look outs have to hold the telephone hand set as they have a trigger on them which if let go sets the klaxon off the same happens if the cable gets cut.

Typically Pee Wee is used where intermediate look outs is impractical it can also be used at night in certain circumstances.   The disadvantage of Pee Wee is the running out of the cable, some locations had Pee Wee cables laid in the line side troughs but as its not armoured suffers damage
