Because if there was a problem with Carlton Central during the week, Carlton Central would back up to Carlton London.
You have answered my question already - Carlton only broadcast during the week and then have a granada compnay as backup for the weekend!

It's easier to put out LWT which is originating most of the ITV Network material.
The point was that Carlton central were supplying 'their' little network of carlton channels with programmes when the power cut happened and nothing was sourced from LWT at the start! So surely it wouldve made sense to have used carlton westcountry as
1) the continuity and idents would have looked no different
2) carlton westcountry is broadcast from cardiff and is the same amount of transmitter/NTL/BT switching away and makes no difference in cost or complexity wether it was lwt or carlton westcountry supplying the feed
3) carlton wont have to pay granada any money for the service they did provide!
4) the rest of the network wouldnt have suffered from getting a 'dirty feed' from london - looked awful on air especially with all the arc switching!
