Tramwaje Warszawskie sp. z o.o. is the sole tram operator in Warsaw, with massive physical infrastructure and a small but observable digital footprint (AS210831). Its operational continuity is critical for city mobility, but the role of its internet resources in tram operations is publicly opaque. The profile is constrained by the absence of network architecture disclosures, named staff, and financial details. Watchpoints center on registry changes, new routing activity, official disclosures, and personnel emergence.

Tramwaje Warszawskie sp. z o.o. is the sole tram operator in Warsaw, running 604 trams over 346 km of track and carrying 252 million passengers annually, while also holding AS210831 and prefix 85.219.213.0/24 as its public internet number resources.
What It Does
Public transport monopoly: The company is the exclusive provider of tram passenger services in Warsaw, owning and maintaining all tram vehicles, tracks, traction power, substations, and passenger information systems. It operates as a commercial-law company wholly owned by the City of Warsaw.
Municipal funding and revenue uncertainty: Public sources do not disclose whether revenue primarily comes from ticket sales, direct municipal subsidies, or a combination; the funding model remains publicly undocumented.
Operating Snapshot
Legal identity: Registered in Poland as a limited-liability company (sp. z o.o.) under KRS 0000145910 and NIP 525-22-56-724, with its headquarters at ul. Siedmiogrodzka 20, 01-232 Warsaw.
Operational scale: In 2024, carried 252,397,918 passengers, travelled 52,070,127 vehicle-km, operated 604 trams, and maintained 346.2 km of track (292.4 km in passenger service), 984 switches, 331.9 km of traction network, and 48 substations.
Network number resources: AS210831 (assigned 2021-08-27) with one visible IPv4 prefix 85.219.213.0/24; no IPv6 space is announced.
Control Surface
Physical infrastructure: Tram vehicles, tracks, switches, traction power network, substations, maintenance facilities, and passenger information displays.
Digital footprint: Official website tw.waw.pl, Public Information Bulletin (BIP) portal, and internet number resources AS210831 with IPv4 prefix 85.219.213.0/24; procurement interfaces and public communication channels complete the observable institutional surface.
Watchpoints
Registry changes: Reassignment, withdrawal, or modification of AS210831 or its associated prefix would directly alter the company's observable internet surface.
New public disclosures: Official publication of network architecture details, cybersecurity incident reports, or procurement of connectivity services would reduce uncertainty about AS210831's role.
Revenue and funding transparency: Publication of financial statements or subsidy agreements by the City of Warsaw would clarify the company's business model and fiscal dependency.
Personnel emergence: The appearance of a named technical or administrative contact in public records or industry forums would provide a monitoring anchor for the company's network operations.

Why tracked: The subject matters because its operational continuity directly affects the daily mobility of hundreds of thousands of Warsaw residents.

Object role: Tramwaje Warszawskie sp. z o.o. is the Warsaw municipal tram operator, responsible for all passenger tram services in the capital. Public sources place it as the sole provider of tram infrastructure, maintenance, and passenger mobility, while registry and routing records associate it with AS210831 and a modest IPv4 footprint in Poland.
Impact note: Disruption to Tramwaje Warszawskie's digital systems could degrade tram service continuity across Warsaw. Network outages or cyber compromises affecting passenger information, operational coordination, or back-office functions could have city-wide mobility impacts. Although the exact role of AS210831 is unconfirmed, any change in its routing or registry status would alter the observable risk surface of a critical municipal operator.
