The Transport Minister Edwina Hart has announced a £24m investment to transform five railway stations across Wales.
The money will be used to improve customer facilities, platforms and access at Aberystwyth, Pontypridd, Port Talbot Parkway, Rhyl and Ystrad Mynach stations.
The ERDF (European Regional Development Fund) will give £17m to the project alongside contributions from the Welsh Government, Arriva Trains Wales and Network Rail.
The news comes as a report found train stations in Wales are less well-used, less accessible and have low-satisfaction levels.
A report from consultants Credo, in association with the Campaign for Better Transport, claims there are "huge disparities" in the quality of train services in different regions of Britain.
In Wales they're less well-used, less accessible and have low satisfaction levels.
A spokesman for the Rail Delivery Group, which speaks on behalf of the rail industry, said:
"While there is always room for improvement, rail passengers are travelling on services that are unrecognisably better when compared to 15 years ago".
Delays of up to one hour on Arriva Trains Wales between Newport and Hereford are expected due to broken down train at Abergavenny.
There is no estimate for when a normal service will resume.
Today's 6.30am Arriva Trains Wales service from Blaenau Ffestiniog to Llandudno Junction has been cancelled. A member of train crew is unavailable.
A yellow "be aware" warning of rain has been issued for Gwynedd and Conwy.
The Met Office says up to 6cm (over 2ins) could fall in Snowdonia between this afternoon and tonight.
Elsewhere between 2cm and 3cm is likely.
Replacement bus service running on Arriva Trains Wales between Pontypridd and Aberdare, and between Pontypridd and Merthyr Tydfil due to over running engineering works between Pontypridd and Abercynon South.
The first trains in each direction have been cancelled. Buses are replacing these trains. Arriva Trains Wales hope that a normal service will resume from around 14:00.
A new type of travel card is being launched in Wrexham today.
The GoCymru smart travel card is similar to a London Oyster Card and will be trialled in Wrexham and Bangor with plans to fully roll the scheme out across the rest of Wales in April.
At the moment the card can only be used on buses but there are plans that in time the scheme will extend to rail services in Wales.
The card is a pay as you go travel top-up card that is used in the place of a traditional paper ticket. It is hoped that the scheme will make it easier and quicker to hop on and off buses.

Trains are now running normally after the flooding at Pontyclun.
