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. Rostering tools schedule workers by availability, preference, or proximity to a work 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 time, and breaks. The Safety Guard Algorithm considers fatigue alongside travel time, working regulations, competence, and site experience. Managers can set alerts for weekly hours, consecutive shifts, minimum breaks, and shift length. Signal also tracks rail compliance items such as passports, visa expiries, medicals, and PTS. Workers can view upcoming work, availability, shift details, travel and hotel bookings, and sign off timesheets through the web app. Timesheets work on mobile or desktop and can include digital signatures, GPS stamps, authorisation, and PDF generation. Shift changes can be sent by email, text, or push notification. Payroll data can be exported through the API or configurable files. Pricing is available on request.
