Signal
What Signal 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 based on availability, preference, or proximity to a site, and can recommend workers for shifts. Fatigue scores cover planned and actual hours and update using factors such as location, travel time, hotel, shift timing, and breaks. Signal can alert managers and workers about fatigue and working-time rules, including weekly hours, consecutive shifts, minimum breaks, and shift length.
Its Safety Guard Algorithm assesses schedules using fatigue, travel time, working regulations, competence, and site experience. Signal tracks rail-related compliance items such as passports, visa expiries, medicals, and PTS. Workers can view upcoming work, shift details, availability, travel and hotel bookings, and sign timesheets through the web app. Timesheets support mobile and desktop use and can include digital signatures, GPS stamps, authorization, and PDF generation. Pricing is available on request; visitors are directed to book a demo.
