PriestmanGoode chairman Paul Priestman said: “We came up with a solution that the train could be transformable, going from off-peak to on-peak, allowing more capacity on board trains.
“We saw that we could increase bicycle capacity while also maintaining social distancing.
“The thought is that you’re using the bicycle bays to keep a distance between people, it’s about making that space useful.
“We’re using the space we imagine is going to be required between people as a useable space for bikes.”
Simon Munk, infrastructure campaigner for the London Cycling Campaign, said: “National rail and the rail companies that operate train stations need to do better on cycle parking, there’s still a massive lack of this in London.”
PriestmanGoode designed the New Tube for London, due to run on the Piccadilly Line in 2023.
But the £1.5 billion fleet of 94 trains replacing the current 1970s-era rolling stock will not be able to run faster due to an ageing signalling system
