DfT said:The Department for Transport also today confirmed the award of £18.5 million from a £150 million government fund for TfN’s smart ticketing programme. TfN will use this to introduce paperless, smart card season tickets for Northern and TransPennine Express and Merseyrail passengers by the end of 2018.

The new Northern TVMs do have an ITSO button (currently disabled) and a device to scan smart readers. If Merseyrail TVMs handle Walrus cards then I imagine they can be easily upgraded. However, what about TPE TVMs?
