Today, still retaining its connection to the UK national rail network through Network Rail, it is the home to many preserved British railway locomotives. The Harry Needle Railroad Company also store and maintain a number of operational lease locomotives on site. As well as the main roundhouse building, Barrow Hill is also home to the former Pinxton Signal box. Relocated after closure, it has since been refurbished and fitted out as per a typical day in its last year of use for Network Rail.
