London commuters face an increase in season ticket prices of 1.6% despite people being urged to return to workplaces.

The cap on the annual rise in most regulated fares is linked to the previous July's Retail Prices Index (RPI) measure of inflation, which was announced by the Office for National Statistics on Wednesday.

Rail fares are usually increased every January, although there is speculation that ministers are considering delaying the 2021 rise due to low passenger numbers.

In addition, Sadiq Khan was forced to agree to increase prices on TfL as part of a 1.6bn government bailout in the wake of the coronavirus crisis, meaning contactless and Oyster card Pay-As-You-Go fares are set to rise by 2.6%.

The UK, Scottish and Welsh Governments regulate rises for around half of fares, including season tickets on most commuter routes, some off-peak return tickets on long-distance journeys, and tickets for travel around major cities at any time.

Rail regulator the Office of Rail and Road said regulated fares went up by an average of 2.7% in January 2020, following the July 2019 RPI figure of 2.8%.

Unregulated fares, including advance and peak long-distance tickets, can be increased at the discretion of train companies.

Examples of potential season ticket prices next year after a 1.6% rise include:

- Brighton to London: Increase of £80 to £5,060

- Barrow-in-Furness to Preston: Increase of £69 to £4,353

- Edinburgh to Glasgow: Increase of £67 to £4,267

Passenger watchdog Transport Focus called for a major shake-up of rail fares to encourage passengers back to the railways following the collapse in demand caused by the coronavirus pandemic.

Chief executive Anthony Smith said a system that fits "the way we live and travel now" is needed, rather than "season tickets designed for city gents in the last century".

He went on: "Our research tells us almost two in three former rail commuters expect to work from home more so we will probably now travel less for work, both commuting and on business.

"The Government must go above and beyond a fares freeze and get train companies to offer a combination of cut-price deals, carnet-style 'bundles', flexible season tickets for commuters and better-value-for-money fares across the board."

Raine Peake, 51, who travelled through London Waterloo station on Wednesday morning, cancelled her £200-a-month ticket from Walton-on-Thames in Surrey to the capital due to working from home more often because of the virus.

"The service is absolutely appalling," she told the PA news agency, giving "cancelled trains" as the reason.

"I think it's already very expensive, and it shouldn't be for profit."
