Public transport operators have started slashing services due to the coronavirus, writes Neil Lancefield.

Train, coach and bus frequencies are being cut amid a collapse in demand and government advice on avoiding non-essential travel.

South Western Railway said it is cancelling trains at short notice as, "like most organisations, we're seeing more staff having to stay at home unwell".

Great Western Railway has announced its sleeper service between London Paddington and Penzance - known as the Night Riviera - will be suspended after Friday "to protect our customers and colleagues".

Robert Nisbet, director of nations and regions at industry body the Rail Delivery Group, said train companies will operate services to "as many places as possible in line with demand".

He added that this must be balanced with "ensuring we are able to maintain staffing levels needed".

The UK's largest operator of scheduled coach services, National Express, said it will reduce its capacity by 80%.

This means it will be running the equivalent of a Christmas Day timetable every day.

This amounts to the removal of around 40 per cent of its bus mileage.

Transport Secretary Grant Shapps has spoken of his desire to avoid "ghost trains", but noted that it may be desirable to keep as many services running as possible to provide space for passengers to comply with social distancing requirements.

He told MPs on Tuesday that rail companies, as well as bus firms and airlines, could be temporarily nationalised to help them through the coronavirus outbreak.

He said good organisations "shouldn't be going bust" as a result of problems caused by the spread of Covid-19.
