Interesting reply to this request. I always thought there were two separate systems in use. Although i think it is more than just one station (Victoria) which uses that second system (ASL IVENCS). Victoria is certainly not the only one. I think many Bakerloo Line and Central Line stations do too.

I use the London Underground every day and i always noticed that at different stations Elinor Hamilton has different wordings.

At some stations (mainly BCV stations) she says:

• "The next train will arrive in one minute. It will be a Victoria Line train calling at all stations to Brixton."

I presume this is the ASL INVECS system.

At some stations (mainly JNP and SSL stations) she says:

• "Victoria Line. The next train to Brixton will arrive in one minute."

I presume this is the Telent system.

But it is the same exact voice (Elinor Hamilton) but there appears to be two different wordings depending on the station. So i was not sure the reason behind this but i was always suspecting that there were actually two separate systems in use (one for BCV stations and one for JNP and SSL stations) and this seems to confirm it.

I remember up until 2019 certain Bakerloo Line stations (eg, Edgware Road, Lambeth North, Kilburn Park, Maida Vale, Regents Park, Warwick Avenue, etc) and certain Central Line stations (eg, Holland Park, Lancaster Gate, Marble Arch, Queensway, Shepherds Bush, White City, etc) had announcements voiced by Pauline Cavilla until they finally got replaced by Elinor Hamilton recently. But when they were replaced by Elinor Hamilton they kept the same wordings (except "Ladies And Gentleman" was removed) so i suspect it is still the same supplier.

So i think it is clear that there are two separate Elinor Hamilton system suppliers in use. One mainly at BCV stations (ASL INVENCS presumably). One mainly at JNP and SSL stations (Telent presumably).

Another follow up annotation.

I have just been going through my hundreds of London Underground station announcements recordings and these are the wordings and scripts for the different systems:

----------------

JNP system (Elinor Hamilton - Current):

• "Victoria Line. The next train to Brixton will arrive in one minute."

• Victoria Line. The train now approaching is to Brixton. Please stand back from the platform edge."

----------------

BCV system (Elinor Hamilton - Current):

• "The next train will arrive in one minute. It will be a Victoria Line service calling at all stations to Brixton."

• "The next train will be a Victoria Line service calling at all stations to Brixton. Please stand behind the yellow line as the train approaches. Use the full length of the platform. And let customers off the train first."

----------------

BCV system (Pauline Cavilla - Discontinued):

• "Ladies and gentlemen. The next train will arrive in one minute. It will be a Victoria Line service calling at all stations to Brixton."

• "Ladies and gentlemen. The next train will be a Victoria Line service calling at all stations to Brixton. Ladies and gentlemen. Please stand behind the yellow line as the train approaches. Use the full length of the platform. And let customers off the train first."

----------------

So indeed it appears that two separate systems are used at London Underground stations currently.

Looking in to it SSL seems to be even more confusing and a mix of the two systems depending on the station. But i think most SSL stations are on the JNP system with only a few on the BCV system.

I know the old Pauline Cavilla version was only ever used at Bakerloo Line and Central Line stations.

I shall have to do a bit more research in to this and try to get an exact list of which stations are using which system as i am not sure about some of the stations served by multiple lines.

Thank you for your information Timothy. Yes I think you're right judging by what you've said. I've only ever been on the Tube once in my life so I haven't a clue myself but if station have two different wordings of announcements, it will most likely by from two different systems
