Project Location: 

Grayson TMS was contacted by a company who were working on the refurbishment of Nottingham Railway station  and the specification was to bring the station’s customer information systems up to date and this included the clocks, whilst still keeping the traditional look of the station.
The current installation consisted of one 36” diameter double-sided clock, nine 24” double-sided clocks and two single-sided clocks, all original “GENT” of Leicester design. Our remit was to refurbish the clocks to the original design, but to improve on the accuracy of the old “Ratchet and Pull” movements.
We started by stripping the clocks back to their components and then bead-blasting the cases back to the base metal of brass, the cases were then treated and powder-coated Satin Black, new toughened safety glass was fitted and the dials cleaned and polished and new LED illumination packages were installed to replace the old fluorescent tubes. Finally we re-bushed the hands and fitted the latest technology movements,  the NBU192T POE networked movements which are powered over Ethernet (POE) and synchronised via a DTS4108.Net Master Clock using Network Time Protocol (NTP) all linked via a GPS4500 GPS synchronisation unit.
We were also asked to refurbish the large clock, which is approximately 1400mm in diameter and is situated in the Ticket Booking Office. We decided to install a DLU140 movement that operates and is powered via Mobaline Time Code and this was linked back to the DTS4108.Net Master Clock which has a programmable line output as well as various other output for different protocols.
As a final touch we were commissioned to renew the gold leaf on the dials of the large exterior 4-sided clock to bring them back to their original lustre and employing the various skills of our experienced engineers throughout the project we were able to deliver a very impressive result.
