On December 14, a First Bus service crashed into a railway bridge on Cook Street, injuring seven people.
It is understood the driver took the wrong turn on the route, resulting in the collision.
A 60-year-old man was seriously injured and a further six people were taken to hospital.
Now, those travelling in the vehicle have contacted Thompsons Solicitors to launch legal proceedings on their behalf.
The firm specialises in bus crashes where multiple passengers have been hurt.
In February 2017, Thompsons represented the families of children injured in a school bus crash in Cumbernauld and a year later, it pursued legal action on behalf of victims of a serious bus accident on the Clydeside Expressway.
In both cases, substantial damages were awarded to the injured.

Patrick McGuire a partner with Thompsons said: “This was truly the nightmare before Christmas for the victims involved.
“Multiple passengers were injured, some very seriously, in an accident that would seem entirely avoidable.
“The Cook Street crash is shocking with a similar accident happening at exactly the same spot in May 2023.
“Our specialist team who have dealt with several crashes of this kind have already been contacted over both incidents and we have opened cases against the companies involved.
“For crashes of this kind to continue to happen is utterly unacceptable and the travelling public deserve so much better.”
