By the 1990s, the railway station's capacity was exceeded on a daily basis, and the 1967 design was deemed inadequate.
Between 1999 and 2002, a major rebuilding project took place, branded as Leeds 1st.
This project saw the construction of additional approach tracks at the western end of the railway station, improving efficiency by separating trains travelling to or from different destinations and preventing them from having to cross each other's routes.
The railway station was expanded from 12 to 17 platforms, with the construction of new platforms on the south side, and reopening of the disused parcels depot to passengers on the north side.

The majority of the track, points and signals were also replaced and the 1967 power box closed – control being handed over to the signalling centre at York.
 The most visible change to passengers, however, was the replacement of the 1967 metal canopy with a new glass roof, considerably increasing the amount of daylight on the platforms.
A new footbridge was also provided, replacing the previous underpass.
Ancillary improvements included a new multi-storey car park and railway station entrance, refurbishing the North Concourse and expanding retail facilities.

A small temporary railway station called Leeds Whitehall was provided to handle some services while the railway station was being remodelled.
This has now been demolished.
