The timetable changes were announced following a 70% drop in passenger numbers on some services.
Specifics are not available at the time of writing, though it appears the cuts will be brought in gradually as demand decreases further. The extent of the scale-back will also vary by operator.
Although passenger numbers have dropped sharply, there have been calls to lay on extra carriages, so that commuters can practice social distancing — something of a novelty on public transport.
The reduction in passenger trains will also give more space to freight trains, helping with the distribution of food and other necessities.
Transport Secretary Grant Shapps has suggested that some routes might be temporarily nationalised, to ensure operations continue. The same may apply to airlines and bus services.
