Until very recently, the railway through Kettering was not electrified, therefore services are currently operated by diesel trains. This is set to change by May 2021, when Class 360 EMU trains are to begin running on the newly electrified section between Bedford and Corby, along its route between London St Pancras and Corby. Diesel Class 222 Meridians and 180 Adelantes are being cascaded in order to run the inter-city services north to Nottingham, Sheffield, Derby, Lincoln and York; these services will continue to call at Kettering.
