Train operators will have to warn you about overcrowded trains
The Transport Minister, Norman Baker, is asking for a 'traffic-light' system in a bid to help travellers avoid crowded carriages. You'll note he isn't demanding more carriages.
Some train companies already provide such information. For example, London Midland have a traffic light system depending on how crowded trains are and they have a section on their website which tells you how likely it is you'll have to stand-up.
Baker said that this practice is: "An important tool for allowing passengers to make informed choices about which trains to travel on, and convincing those passengers who can change their travel patterns to do so."
A spokesman for the Association of Train Operating Companies said: "As train companies, we want our passengers to enjoy a comfortable journey, which is why many operators already provide information about which services are busiest. Compared to the mid-90s, there are now 4,000 more services a day but we will continue working with the DfT to get longer and more frequent trains on to the railway."
