Northstar, 16 October: new housing fields, better links in the west, limits of extra stops

Northstar gained residents between the first and last population reading of 16 October 2026, but stayed below two million and lost population after a higher intermediate figure. The same day the building agent placed new metro stations, set up two bus lines, added several industrial exits and zoned three new housing fields. Results differed by area: measured traffic flow improved in the west, labour shortages persisted in the northwest, and extra metro stops did not draw more move-in than comparison areas everywhere. All times are Berlin time; the sources are readings and build logs taken at different times, not one joint snapshot of the city.

Residents and jobs

The net gain over the day is about nine percent, but by evening about 84,000 residents were missing against the intermediate figure. Move-in came in bursts, and the build log records two crashes with restarts, so comparisons across those points are not undisturbed trials. The intermediate figure is not claimed to be the day's exact maximum.

Unemployment stood below the last documented target band, yet some positions for highly educated workers remained open. The overall figures do not show that qualification, home and commute match.

Thirteen metro stations, different outcomes

The stations were built in the southwest, east, south, northwest and southeast, with later ones closing further gaps. Line 3 grew to about 17.9 kilometres and line 1 reached about 34.5 kilometres after the connection of the northwestern stop NG. The stop sequences were read back as connected. That shows neither a sufficient number of trains nor a population effect.

Early on, stations were judged against the city population, which overstates a local advantage when other empty homes fill during a general move-in phase. Later the comparison used surrounding circles and matched buildings. Around NG, households in the matched buildings rose by about a quarter or more, far more than in the comparison circle. That points to a local advantage, but it is an observation amid ongoing changes, not isolated proof of the station's share.

At S6 the matched group fell, while its comparison circle rose. A nearby metro stop did not reduce vacancy in the short term here; the cause of the weak move-in is open. Further stops are therefore meant to close useful routes between homes, jobs and existing lines, not merely to touch large vacant areas.

An eastern metro depot was built and extended, and the western depot gained places. Read-backs showed more trains in service and, for a time, an end to some vehicle shortage reports. Additional tracks, however, reported missing network access although their capacity already counted in the fleet display. Connection work stayed partly incomplete: some track ends were joined, other plans were dropped because of collisions or unsuitable geometry.

Roads in the west

A cypress link with a bridge crossing was built in the north, followed in the west by a further connection to Lavendelstraße and a bridge from Erlenbachstraße to Rotbeerenstraße. Existing industrial buildings were given up for this.

The flow value is a game metric between zero and one, not a speed; higher means better flow. The area stayed the same, but the rebuild changed the number of segments. In the control corridor the value fell slightly, so the local gain goes beyond a general improvement of the city. The share of each link or signal change is not isolated.

Around the port, a new half junction and changed junctions were built, and in the stored corridor comparison the western section of Sekretärstraße showed a higher flow value afterwards (0.142 before, 0.251 after), though a later sample already showed load on the new connection. In the northwest the improvement was weaker, with low flow values and rising labour reports. A city-wide cure for congestion is not shown.

Buses between housing and industry

Line 17, "Zubringer Südost", was set up in the afternoon with a loop of roughly 13 kilometres. In the examined southeast area, reports of missing uneducated workers fell by about two thirds, while in the rest of the city they rose. Late in the evening the line's buses carried less than a third of their places at once; that is passengers aboard at one moment, not daily trips or newly employed people. Road building, general move-in and other lines ran in parallel, so a pure bus effect is not isolated.

The western feeder was postponed because it would have been stuck in traffic. After the road improvements, line 18, "Zubringer West", followed at about 22:06 with ten connected stops and an initial loop of about 12.68 kilometres, supported by a new bus depot. The short late-evening observation is a first finding only.

Three housing fields

In the evening building shifted to better-placed residential land. Earlier free lots had triggered little construction despite positive demand; unfavourable locations near industry and unsuitable remnant plots were examined as explanations. That diagnosis motivated the new fields; it is no proof for every single vacant lot.

Field Nord 1 received roads, a rail crossing, power and local services, and was zoned for dense housing in two steps. At the day's last field count it held 44 residential buildings and no free lots; the other two fields had been developed more recently. The northern field also received a new road connection at the map edge; how many residents move in through it was open at day's end. Capacities assumed in plans are not counted as population.

Water, cash, performance and status

Two extra groundwater pumps brought only a small capacity gain; twelve surface pumping stations with new shore access followed in the morning. Reserve for further growth still has to be measured against consumption and effective capacity.

The residential tax rose in steps and was returned to six percent in the evening after the planned abort rule triggered. Because move-in phases and tax changes coincided, no isolated tax effect can be derived. The late cash reading was inside the documented band; the exact figures are in the table.

The build log records an extension of the long-term goal to five million residents, with the wish for a workable simulation at speed 1. The projections made for it are planning assumptions, not a load test achieved. The qualified performance source has no usable readings for the whole of 16 October, a full-day gap of unknown cause; no CPU efficiency gain is claimed for this day. Open are verified move-in to the new buildings, lasting traffic flow, matching commutes and stable supply, together with comparable performance windows.
