What it is
Signal is a cloud-based workforce platform for rail, construction, and plant teams, including contractors, train operators, plant providers, and staffing agencies. Its rostering tools schedule workers by availability, preference, or proximity to a site, and can recommend people for shifts. Fatigue scores update in real time for planned and actual hours, using factors such as location, travel, hotel, shift time, and breaks. The Safety Guard Algorithm also weighs working regulations, competence, and site experience. Managers can set alerts for weekly hours, consecutive shifts, minimum breaks, and shift length. Signal tracks rail compliance items such as passports, visa expiries, medicals, and PTS. Workers can view upcoming work, availability, travel and hotel bookings, and shift details through the web app, then sign off timesheets. Timesheets support digital signatures, GPS stamps, authorisation, and PDF generation. Pricing is available on request, and the pages direct visitors to book a demo. Signal lists Android, iOS, web, and API platforms.
