ATO

Trains running through the Thameslink 'Core' in central London are using Automatic Train Operation (ATO) with European Train Control System (ETCS) in regular service. … Using ATO will enable GTR to reach the intended 24 trains per hour target between St Pancras International and Blackfriars.

Interestingly, the nature of the available stolen data means the typical victim of an ATO attack varies slightly depending on whether a bank or a retailer is under attack.
