Knaresborough North Yorkshire 3rd September 2022

It may not be a steam train but it certainly produced plenty of smoke which lingered in the gloom of the tunnel for quite a long time!

This working out of Knaresborough is 2C24, the 10.29 Leeds to York service, and Northern Class 170 diesel multiple unit 170475 has just departed from the north end of the station through the tunnel.
