The largest rail strike for a generation caused severe disruption on Tuesday, with more cancellations happening on Wednesday.
Many passengers’ journeys took several hours longer than normal, while those who chose to travel by car instead were greeted by a surge in traffic.
Just a fifth of trains ran on Tuesday and half of all lines were closed.
Last trains were much earlier than normal, such as London Euston to Glasgow at 1.30pm and London King’s Cross to Edinburgh at 2pm. The network was due to shut down at 6.30pm.
The chaos will continue on Wednesday, with only 60% of trains running, mainly due to a delay to the start of services as signallers and control room staff are not doing overnight shifts.
Some 40,000 members of the Rail, Maritime and Transport (RMT) union at Network Rail and 13 train operators walked out on Tuesday in a bitter dispute over pay, jobs and conditions.
RMT members are leading the way for all workers in this country who are sick and tired of having their pay and conditions slashed by a mixture of big business profits and Government policy
Mick Lynch, RMT
“Our members will continue the campaign and have shown outstanding unity in the pursuit of a settlement to this dispute.
“RMT members are leading the way for all workers in this country who are sick and tired of having their pay and conditions slashed by a mixture of big business profits and Government policy.
“Now is the time to stand up and fight for every single railway worker in this dispute that we will win.”
Much of Britain had no passenger trains for the entire day, including most of Scotland and Wales, the whole of Cornwall and Dorset, and places such as Chester, Hull, Lincoln and Worcester.
Prime Minister Boris Johnson told a meeting of the Cabinet that reforms are vital for the rail industry and passengers.
He said: “I say this to the country as a whole, we need to get ready to stay the course.
“To stay the course, because these reforms, these improvements in the way we run our railways are in the interests of the travelling public, they will help to cut costs for farepayers up and down the country.”
Usually busy stations such as London Euston and Birmingham New Street were nearly deserted except for union picket lines.
Many people worked from home rather than travelled to offices.
Retail analysts Springboard said footfall in central London was 27% down on last Tuesday, while city centres outside the capital suffered an 11% reduction.
Those who had to travel faced skeleton train timetables and increased traffic on the roads.
Electrical engineer Harry Charles said his normal 10-minute journey to work by train to London Bridge took him 90 minutes.
The 30-year-old, from Lewisham, south-east London, said: “Obviously I had to wake up early and left my house at 6am.
“I am with the employees who are striking because their money is not going up and the cost of everything is rising.
“The strike has caused a lot of hassle for people but everyone wants be able to eat.”
At Liverpool Lime Street station, couple Sheila and Steve, who did not want to give their last name, were due to travel to London for a theatre trip costing £500.
Steve said: “The 8.47am train has been cancelled and we’re just keeping our fingers crossed for the next one at 9.47am.
“I think they have got the right to strike but this seems a bit unfair on other people.”
At Birmingham New Street station, a few would-be passengers and commuters were trying to work out their travel plans, gazing at timetables on their phones and the departures board on the main concourse.
Carol Hutchinson, who was on her way back to the Lake District after coming off a six-hour flight from Egypt, landed in the UK to find her direct train from Birmingham International station cancelled.

Having made her way to New Street, she was waiting to board what appeared to be one of the few trains still running.
“I think it’s going to be standing room only… I’m not even sure I’ll get on with my suitcase,” she said.
London Underground services were also suspended on the vast majority of lines due to a walkout by workers.
Figures published by location technology firm TomTom show the level of road congestion at 11am was higher than the same time last week in several cities.
In London, congestion levels increased from 38%% on June 14 to 51% today.
Other locations with worse traffic included Cardiff (from 24% to 29%), Liverpool (from 24% to 30%), Manchester (from 27% to 34%) and Newcastle (from 18% to 20%).
The figures represent the proportion of additional time required for journeys compared with free-flowing conditions.
There were also severe queues on outer London sections of the M1, M4, A4 and A40.
People trying to travel around the capital faced long queues for buses.
Uber hiked its prices amid a spike in demand, with a three-mile journey from Paddington to King’s Cross estimated to cost £27 at 8.45am.
Strikes are also planned for Thursday and Saturday.
Pupils and parents were being urged to make an alternative plan for getting to school for A-level and GCSE exams.
Mr Lynch warned that the dispute could continue for months.
The union has been asked by Network Rail to attend formal consultation talks next month on introducing “modern working practices”.
Network Rail official Tim Shoveller said the changes will mean “dumping outdated working practices and introducing new technology”.
He added: “We expect this will reduce roles by around 1,800, the vast majority of which will be lost through voluntary severance and natural wastage.”
Talks between the RMT, Network Rail and train companies will resume on Wednesday.
No meetings were held on Tuesday as the first strike went ahead, crippling the rail network.
A Department for Transport spokesman said: “These are desperately needed reforms that modernise the railway and put it on a sustainable footing for passengers and taxpayers.
“Unions have shut down big parts of the rail network, hitting local businesses and unfairly cutting people off from hospitals, schools and work.
“However, early data shows that unlike in the past many people now have the opportunity to work from home, so we haven’t even a rush to the roads, as traffic has instead gone online, which means the unions aren’t having the overall impact they might have hoped.”
