Station facilities will also reopen, including the shops and toilets, but some of the main concourse will remain closed.
Passengers should continue to use Glasgow Central’s Hope Street and low-level entrances while the main doors are blocked off.
Train services from the low-level platforms, which run to Balloch and Milngavie in the west and Motherwell and Cumbernauld to the east, were the first to resume after the blaze.
The news came as a multi-million pound fund to support businesses affected by the fire opened for applications.
The Fire Recovery Fund is being administered by Glasgow City Council, using funding from the Scottish government’s £10m commitment to support the recovery from the fire.
All eligible businesses displaced due to the fire and surrounding buildings directly affected by the fire will qualify for support.
Three levels of funding support will be available – £25,000 for each of the 73 businesses who lost their premises in Forsyth House, £15,000 for each of the 78 businesses in the current cordon and £2,000 for each of the 700 businesses within the initial cordon.
