Welado Sthk

What Welado Sthk does

Welado STHK AB is a Swedish specialist consulting firm (founded 2009 as Stockholmskonsulterna, rebranded Welado STHK in 2024) focused on railway signaling, ERTMS/ETCS deployment, rolling stock, public transport IT, and infrastructure projects for Nordic clients. The company delivers expert consulting across the full project lifecycle — from planning and regulatory approvals (GOP/TSS/TSB) through testing, certification, and maintenance support — for both trackside and onboard systems. Since 2022 it has operated as a wholly-owned subsidiary of the Finnish-Swedish Welado Group, giving it access to over 300 consultants across Sweden, Finland, and the broader Nordic region through 12 offices.

The firm's revenue model is professional services / billable consulting hours delivered to a relatively concentrated set of government transport authorities and railway operators. Core service areas are ERTMS and railway signaling, public transport signaling (metros, trams, light rail), vehicle procurement/inspection/maintenance, infrastructure (roads, bridges, tunnels, construction management), IT solutions for public transport (traffic information, timetables, positioning, monitoring, system integration), and management/signal strategy consulting. Reported FY2024 revenue was 62 Mkr SEK, supported by 37+ experts across five Swedish offices (Stockholm, Göteborg, Malmö, Örnsköldsvik, Stenungsund, Luleå) plus Welado Group offices in Finland.

The go-to-market is direct enterprise/field sales into long-cycle public infrastructure programs, with named engagements for Trafikverket (ERTMS rollout), SJ (ETCS onboard support), Trafikförvaltningen (Stockholm metro/Roslagsbanan), Transitio (vehicle QA), Infranord, Västtrafik, Göteborgs Spårvägar, NCC, and Enviro Systems. Customer relationships are anchored to multi-year public procurement cycles rather than transactional sales, and the offering is positioned as a bridge between clients and equipment suppliers.

Broad incumbents

• COWI: Danish-headquartered engineering consultancy with Nordic and global rail/infrastructure capabilities. Competes for similar large-scale transport and rail signaling projects in the Nordics, with deeper international reach than Welado STHK.
• WSP Sverige: Global engineering consultancy with strong Nordic presence in rail, signaling, and transport infrastructure. Competes for Swedish rail/infrastructure tenders and brings larger multidisciplinary resources to projects Welado STHK also bids on.
• AFRY (ÅF): Swedish-origin engineering consultancy with extensive rail, signaling, and infrastructure capabilities across the Nordics. Directly competes for the same Trafikverket and Swedish PTA engagements but at much larger scale and with a broader industrial portfolio.
• Sweco: Leading Nordic engineering, design, and consulting firm with a dedicated rail/infrastructure practice serving Swedish PTAs and Trafikverket. Overlaps with Welado STHK on infrastructure and rail consulting, but operates at significantly larger scale across multiple verticals.
• Ramboll: International engineering consultancy with Nordic roots and significant transport/infrastructure practices. Overlaps with Welado STHK on rail and public transport consulting for Nordic PTAs, though Ramboll serves a much broader portfolio of clients and sectors.

Direct peers

• Hitachi Rail: Global rail signaling, ERTMS/ETCS, and rolling stock provider active across Europe. Comparable to Alstom/Siemens as a signaling supplier whose products Welado STHK supports, while also fielding its own consulting/service capabilities in the same Swedish programs.
• Alstom (incl. former Bombardier Transportation): Global rail signaling and rolling stock supplier whose onboard ETCS systems Welado STHK tests and integrates for SJ and others. Works closely with Welado STHK on Swedish ERTMS/ETCS deployments, both as partner and as adjacent capability owner.
• Siemens Mobility: Major rail signaling, ERTMS, and rail automation technology provider. Operates as both a supplier partner and competitor for ERTMS deployment projects in Sweden where Welado STHK provides consulting and test management.

Regional players

• Rejlers: Nordic engineering consultancy headquartered in Sweden with rail, infrastructure, and industrial automation practices. Comparable in size and Nordic focus, competing for similar PTA and infrastructure clients in Sweden, Finland, and Norway.

Others

• Trafikverket Konsult (in-house): Sweden's transport administration performs much of its own ERTMS and rail infrastructure project management in-house, competing with Welado STHK for project leadership on flagship programs and setting the bar for pricing on outsourced work.
