The project portal for partners who need a straight answer.

Most people arrive at Adapt-a-Modal with the same three questions, in the same order. This page answers all three — what the system is, why it matters, and exactly what Diggs Development Group Inc. is asking of you — and then gives you one place to respond.

The Short Briefing

Everything a first meeting usually spends an hour establishing.

Read this in three minutes. Every claim below links to the detailed material behind it, so you can verify the case before you commit any time to it.

What is Adapt-a-Modal?

Adapt-a-Modal is a single elevated transportation corridor built to carry many missions instead of one. One permanent adaptive spine — a light rail or monorail guideway — hosts interchangeable units that ride the same track: passenger cars, consignment freight, cold-chain medical cargo, a mobile medical logistics unit, fire prevention and hazmat response, mobile water treatment, and resource protection teams.

The corridor is built once. The mission running on it changes by hour, by season, and by emergency. Passengers move in the morning peak, freight and cold-chain cargo move midday, and the same guideway carries emergency units when a road network is blocked or a storm closes ground access. Three station types — regional hub, community, and local stop — bring the system down to street level with civic services and local business space attached.

Why does it matter?

Conventional infrastructure recovers its cost from one function. A commuter line carries commuters; a freight spur carries freight. Adapt-a-Modal spreads one fixed corridor cost across many functions and many revenue paths, which is the whole argument behind it:

Adapt-a-Modal Value over time = the adaptive spine × the sum of its service functions over time × adaptability − total cost

That matters in three practical ways. It improves the return on a public dollar, because the same structure earns from fares, station and vendor leases, freight, healthcare and emergency service contracts, airport partnerships, tourism, advertising, parking, and renewable energy. It holds up when conditions change, because severe weather, road closures, and emergencies are operating modes for the corridor rather than interruptions to it. And in the Lehigh Valley it connects assets the region already owns — the river corridor and the D&L Trail, two airports, hospitals, warehousing and distribution, and water treatment — across Carbon, Northampton, Lehigh, Bucks, and Montgomery counties, without taking the trail away from the people who use it.

What does DDG want from me?

Not a funding decision on a first call, and not a signature on anything. DDG is asking for a working conversation, and then one concrete commitment that depends entirely on who you are.

The concept stage is finished: the system is defined, the unit fleet is drawn, the station typology is set, the revenue model is documented, and the public-benefit case is published. The next stage is a feasibility and corridor study — alignment, ridership, cost, and right-of-way — and that stage needs three different kinds of help. Capital partners fund it. Public agencies open the door to it and supply the data it runs on. Institutions and industry operators tell it what service they would actually buy. Pick the track that matches your role below; each one states the ask in one sentence.

Partner Tracks

Three roles, three specific asks.

Find yourself in one of these three columns. Each states who it is for, what DDG brings to the table, what DDG is asking for, and the next step — so you know what a conversation commits you to before you start one.

Track A

Capital & Investment Partners

Private investors, infrastructure and development funds, family offices, corporate strategic partners, and sponsors.

What DDG brings
A fully documented concept — system definition, unit fleet specifications, station typology, a thirteen-path revenue model, and a public-benefit case — endorsed by the International Monorail Association since 2021. It is the material an underwriting team needs to scope a feasibility phase rather than a pitch deck.
The ask
Fund or co-fund the feasibility and corridor study that converts this concept into engineered, costed scope — and where it fits, sponsor the presentation program and open introductions to co-investors.
Your next step
A short briefing call. DDG follows it with the investor letter, the sponsorship package, and the study scope under discussion.
Request the investor briefing
Track B

Public Sector & Agencies

Federal, state, county, and municipal leaders; transportation agencies and authorities; planning commissions and metropolitan planning organizations; economic development and emergency management offices.

What DDG brings
A public-facing explanation package built for councils, board meetings, hearings, and constituents: one visual summary of why the elevated approach is proposed, how it fits alongside the canal and trail rather than replacing them, and how it ties to emergency access, public health, tourism, and economic development.
The ask
A place on the agenda — a briefing to your council, board, or planning body; a letter of support or resolution of interest; consideration of the corridor in long-range planning work; and access to the corridor, right-of-way, and ridership data a feasibility study depends on.
Your next step
Name a date and a format. DDG delivers the presentation, printed handouts, and the visuals your body needs for the record.
Request an agency briefing
Track C

Institutional & Industry Partners

Hospitals and health systems, universities, airports, logistics and warehousing operators, utilities and water authorities, emergency services, and rail and transit technology suppliers.

What DDG brings
Units already configured to specific missions — the MMLU mobile medical logistic unit, refrigerated and cold-chain pharma cars, the FPH-3 fire and hazmat unit, the WTU-2 water treatment unit, and the RPT-2 resource protection unit — plus spur-route logic that reaches the facilities you already operate.
The ask
A letter of interest describing the service you would actually use, a technical review of the relevant unit against your operating requirements, and a named operational contact for the study phase.
Your next step
A technical review session with your operations team on the unit and spur route that touches your facility.
Request a technical review

Project Stage

Where the project actually stands.

Partners deserve to know which stage they are being invited into. Adapt-a-Modal is a documented concept moving toward feasibility — not an approved, funded, or permitted project.

Complete Concept & documentation

System definition, unit fleet, station typology, regional corridor map, revenue model, public-benefit case, economic plan, and the executive e-book.

Open now Feasibility & corridor study

Alignment options, ridership and freight demand, order-of-magnitude cost, right-of-way and utility review. This is the stage every ask on this page is pointed at.

Next Preliminary engineering & environmental

Technical design, environmental and trail-impact review, station siting, and the public involvement process that has to run alongside them.

Future Funding, delivery & operations

Capital assembly, procurement, construction, and an operating model built on the revenue and service contracts identified in the concept stage.

DDG develops, coordinates, and presents infrastructure concepts. Study, engineering, construction, and operations are delivered with partners — which is why the asks above are for participation in stage two rather than for a commitment to the whole program.
