Passenger Information Displays for the Central Estonian Rail Network
The challenge
The problem to solve
Edelaraudtee AS, infrastructure manager of the Tallinn-Väike–Viljandi line, ran public procurement 278143 in 2024 for a unified real-time passenger information network covering every stop on the line, from Tallinn-Väike to small rural halts. The requirement: one technical solution across the whole network, purchased under public procurement rules, operating year-round in Estonian outdoor conditions, integrated with Elron's live passenger information system, and backed by a long-term maintenance agreement.
The solution
What Ampron delivered
Ampron delivered as GoTrack OÜ's subcontractor — GoTrack won the tender as main contractor. Two outdoor LCD models cover all 24 stops: 21 units of the YT-S49F dual-sided 49" (2,500 cd/m², −40°C to +55°C) and 7 units of the YT-S55T outdoor vertical 55" totem. 26 were installed under the tender and two more 49" units followed in 2026. All displays run AmpronLED — Ampron's proprietary display communication protocol — which receives Elron's passenger information feed and renders live schedules, platform assignments and service updates consistently across the entire fleet. Following installation, Ampron and Edelaraudtee signed a direct technical support agreement covering the full fleet with defined response times, on-site maintenance and a spare parts inventory.
A 24-stop rail line with manual or paper-based passenger information requires staff presence at every halt to update boards. AmpronLED eliminates that dependency — Elron's central feed updates all 28 screens simultaneously. At rural halts with minimal staffing, live information that runs without staff intervention is the difference between a functional station and an unmanned platform with stale paper timetables.
Outcomes
Results
- ✓ 28 outdoor LCD screens at 24 stops, one information layer for the whole line
- ✓ Live passenger information from Elron's timetable feed rendered on every platform via AmpronLED
- ✓ Hardware rated −40°C to +55°C, 2,500 cd/m² — readable in direct summer sun and low winter light year-round
- ✓ Long-term direct support agreement signed with Edelaraudtee AS, independent of the main contractor scope
- ✓ Delivered via public procurement under GoTrack OÜ as main contractor — standard Baltic infrastructure procurement shape
