Transport bosses will meet later to discuss delays to the upgrade of Bradford's railway stations.
A £5.6 million refurbishment of Bradford Interchange is likely to be 13 months later than planned. Its projected completion date will therefore move back, from September 2020 to October 2021.
A report, published last week by the West Yorkshire Combined Authority, blamed "a shortage of resources" for a nine-month delay in the submission of the required outline business case.
Planned improvements at Bradford Interchange include a new drop-off area, improved concourses, and better accessibility.
Separately, a £17.3 million upgrade of Forster Square Station is nine months behind schedule.
The refurbishment would include improved waiting rooms, new toilet facilities, and lifts to better connect the station to the city centre.
Cllr Alex Ross-Shaw, Bradford Council's member for Regeneration, Planning, and Transport, insisted the project remained value for money.
