NHS staff in Wales are being offered free travel on Transport for Wales rail services with immediate effect, the company has announced.
NHS workers will just need to show their work ID to access services to get themselves back and forth to work until 30 April.
Public transport is to operate on a reduced scale throughout Wales because of the coronavirus pandemic.
However the reduced service has led to crowding on some trains.
New timetables are now in place for trains and buses until further notice.
Announcing the move for NHS workers, Transport for Wales (TfW) said: “At Transport for Wales our primary focus is keeping our colleagues and customers safe, and to keep key workers moving.
“From Monday 23 March, Transport for Wales will provide all NHS workers free travel to and from work until 30th April on production of their NHS ID.”
Astatement on its websiteadded: “We are doing all we can to keep vital services running, so that emergency service staff who are using our trains and key workers are to travel in safety with confidence.”
Some passengers were reporting difficulties in maintaining social distancing on trains on Monday morning.
Hospital worker Emma Lamorte highlighted the situation on Twitter and called for more trains.
However, other travellers in Wales reported quieter than usual carriages.
Commuter Aurora Heathfield from Bridgend, said there was an “eerie feel” on the train to Cardiff on Monday morning with carriages much quieter than usual.
“It would usually be pretty busy and you’d be looking for a seat. There was three people in my carriage,” she said.
Jake Newberry from Cross Keys, Caerphilly county, said there was “hardly anyone” on his train on the Ebbw Vale line and he had expected to see more people due to the reduced timetable.
Alex Varney said the train from Barry to Cardiff was also quiet with the conductor providing advice over a speaker rather than walking through the train to check tickets.
“It was nice and quiet and nice to have some space,” he said.
“Everyone was calm and pleasant and just going through their day.”
A TfW spokesman said on Monday afternoon: “Whilst some services were busy this morning, on average most were 50-60% full. However, we will continue to prioritise peak periods services in order to ensure we do not create overly busy services.
“”We will be monitoring the situation on a daily basis and increase capacity where necessary but we do strongly urge customers to carefully consider whether they do have to travel so that priority can be given to key workers.”
Why are services being reduced?
The changes reflect the fall in demand, reduced availability of staff and the latest public health guidance, transport companies said.
Transport Minister Ken Skates said it remained “crucial” to keep some services going for key workers and supply chains.
“This action aims to balance the current significantly reduced levels of passenger demand as people follow the guidelines to socially isolate with the need to reduce the number of people required to run the network,” he said.
“This contingency measure will help to ensure there are enough staff to keep services running over the coming weeks and months.”
“We also know that our bus services play a vital role in keeping the country running and ensuring key sector personnel get to work,” he added.
“Our objective has been to focus resources on where we know they are needed most at this time.”
In north Wales, Arriva Bus is runningan emergency servicebut will still operate key routes “to ensure customers can continue to access critical services”.
Cardiff Bus isnow following a Saturday timetablefor most of its services across the capital with the exception of some services which are running normally. School buses will continue for eligible children.
AllNewport Bus servicesare also now following a Saturday timetable in “these unprecedented times”, the company said.
It added: “We will maintain bus services for our customers for as long as we are able to.”
“This timetable has been designed to be as resilient as possible, whilst ensuring we balance a reduction in demand, availability of our people and the need to support key workers such as health, food retailers and delivery teams,” it said.
The operator said advanced tickets were now eligible for refunds.
