Operating, checking, prior and open-field markets stay visible instead of being disqualified.
National Loop opportunity + Boring Company activity screen
Keep every city in the ranking. Flag what TBC is already doing.
Opportunity and TBC status are separate layers: active markets remain useful expansion or partnership cases, Atlanta remains the strongest strict open-field case, and Los Angeles joins as a flagged TBC-return opportunity.
West Midtown and Buckhead create two short MARTA-feeder tests without a verified TBC project.
TBC's Hawthorne test track is active; public passenger concepts are dormant and substitutes are live.
New open candidates include Columbus, Indianapolis, Philadelphia, Detroit, Minneapolis and Anaheim.
32 scored metros · 33 public TBC signals
Rank the opportunity first; use TBC status as context.
“Open field” means no verified public activity in the reviewed sources—not proof that no private conversation occurred.
Assumed Comparative 0–100 judgments from public evidence; not an engineering approval.
Boring Company activity watch
Flag active work, diligence, presence and old proposals separately.
A prior pitch is not an active project; a challenge finalist is not construction. The distinctions make TBC involvement usable rather than disqualifying.

Checked through 20 July 2026 against TBC's current portfolio, the 2026 Tunnel Vision challenge and results, and indexed government / transit / airport records. Absence of public evidence is not proof of zero private contact.
Atlanta · open-field case · two initial segments
Choose between stronger mobility value and a smaller execution test.
Both are shorter than two route miles, feed MARTA and avoid duplicating its north–south rail spine.
West Midtown Link
Westside Provisions ↔ Arts Center MARTA
Closes a rail-access gap for a fast-growing mixed-use district and creates a useful MARTA feeder.

Scenario lab
Fare revenue does not finance the full build by itself.
Adjust the assumptions. Every output below is a screening scenario, not a forecast or bid.
Capital assumptions

Positive operations do not prove capital financeability. Station cofunding, land, value capture or public availability payments are still needed.
Feasibility gates
Six questions decide whether this remains a map or becomes a project.
- 01STOP / REDESIGN
Fire and evacuation
Can the local fire authority approve twin EV tubes, cross passages, smoke control, egress, towing and thermal-runaway response?
- 02DROP / REALIGN A
Portal + transit interfaces
Can the preferred pilot secure portal parcels and cross utilities, railroad / highway constraints and the transit-station zone safely?
- 03REALIGN
Continuous subsurface rights
Can the route stay under streets and committed anchor parcels without foundation, utility or title conflicts?
- 04STOP IF ADVANTAGE FAILS
Ground truth
Do borings locate competent ground without long reaches of weak saprolite, abrupt rockhead or water-bearing fractures?
- 05LIMIT THE NETWORK
Calibrated capacity
Can a link sustain at least 1,500 passengers/hour/direction with under five-minute queues and safe event operations?
- 06NO FULL BUILD
Commercial support
Will at least two major anchors contribute station land, capital or recurring availability revenue?
Next 90 days
Spend the first dollars on killing the wrong alignment early.
Validate the need
Acquire observed OD and travel-time data; benchmark MARTA, buses, shuttles, walking and every funded substitute.
Lock station partners
Obtain written interest from the transit agency, city departments and at least two private destination anchors.
Run fatal-flaw engineering
Map subsurface title, utilities, initial borings, jurisdictional interfaces and fire-life-safety requirements.
Select one pilot
Issue an independent Class 4/5 cost and capacity review, then choose Pilot A or Pilot B—not both.
