Slightly off topic I know, but the last two evening services out of London to Both Chippenham and Bath have been replaced by buses from Swindon for about the last 5 years on most nights of teh week. I realise that engineering work is neccessary but this has been going on for 5 years. Surely whatever NR» are doing ought to have been completed by now. Does anyone know when the bus replacements will end.
I suspect that they have become a habbit. NR assumes that they will have an extra three hours every eveneing and FGW▸ probably finds i cheaper to hire a couple of coaches than to run the trains. Using coaches also allows it to close teh stations early
The bus connection to Chippenham and Bath out of the last two weekday Paddington to Bristol services has always been a frequent feature of the service in the 18 years I have been using these trains. I use them probably twice a month, and I experience the bus substitution on perhaps one occasion in five. I assume that it makes way for routine maintenance engineering work rather than any specific renewals or improvements. My usual strategy is to check in advance whether it's going to be a through train to Bath, and if not, do a car positioning move to Swindon in the morning.
I don't think there is any financial benefit to FGW in running coaches, since they still have to run the trains through to Bristol on the route via Parkway.
