Island Line CIS and PA installation
Public Address and customer information systems at five Island Line stations, connected by 4G and a Wi-Fi bridge in place of new cable routes.
Case study
Customer information system displays at twenty stations on TDM-made brackets and columns, with a complete CIS and PA system at Parson Street.

TDM installed customer information system (CIS) displays at 20 stations for GWR, from Oxford and Exeter St David’s to small rural stations, and a complete CIS and Public Address (PA) system at Parson Street.
The stations were spread across the network and differed in size, infrastructure and setting. Work at the major stations had to cause minimal disruption to service. Chippenham, Maiden Newton and St Erth are listed, and needed heritage-compliant finishes.
