Train drivers brought the rail system to a standstill in England on Thursday, and also affected services in Wales and Scotland.
On Friday the RMT union started a new 48 hour strike with bosses advising the public only to travel if "absolutely necessary".
The UK government has now proposed anti-strike laws requiring fire, ambulance, and rail services to have minimum service levels.
Reporting from commuter town Sevenoaks, Newsnight Correspondent Anna Collinson looks at what the legacy could be of the current strikes on the railway. Do they risk permanently putting the public off trains, or will the impact of the strikes prove inconsequential compared to broader challenges facing the network?
