The obvious place to get a picture of the Hertfordshire Railtours 1Z37 'Cattal Grid' railtour on 1 July 1995 was passing through Cattal station. So here are 37517 & 37095 slowing for the token exchange at the eponymous station with what is obviously the 'Cattal' part of the tour. The 'Grid' part was the York to Newcastle and return section behind 56006. The 37s worked round the Harrogate loop, and 90020 was provided for the Kings Cross to York and return sections.
