Preservation Modifications
In 2021 the seating was reconfigured from predominently "airline style" to mainly facing bays, more suited to a tourist operation. Covid-19 plastic dividing screens were also added at the same time in between bays.

Preservation Information
144004 was preserved for the Aln Valley Railway in 2020 but had to be held in storage first at the Keighley & Worth Valley Railway and later the Wensleydale Railway before final arrival by road at its preservation home in December 2020. On arrival it became the 13th Class 144 to be preserved.

Preparations for service involved the fitting of Covid-19 plastic screens and the moving of seating into facing bays of four, following which 144004 operated its first passenger services in June 2021.

The following year saw 144004 operate a number of new "Pacer Operating Days", with 27 days being included in the calander. The set was to work them all as repairs to sister 144016 were still ongoing.

During 2022 the set was repainted into Regional Railways livery, one of the first Class 144's in preservation to be repainted and also the first time that livery had been seen in preservation on a second generation vehicle. It's first two years in use were sucessful but fuel contamination was an ongoing issue.

In 2025, the set had a major exam as part opf its cycle, with the works being undertaken mainly by young volunteers under supervision/guidance. The set was used regularly on all the railway's off-peak services with 100% availability, despite an issue where it would not taske power in forward gear having to be resolved.

144004 remains in use and available for service.

Future Plans
To maintain in service on off-peak duties.
