TDI Greenway

Background

In February 2025, TDI Greenway and RDC partnered to strengthen growth for rapidly deployed light metro, light-rapid transit, very light rail (VLR) and tram solutions on secondary freight and passenger routes worldwide. The joint venture led to a merger between TDI and RDC’s rail mobility division, Pop-Up Metro (PUM), LLC. TDI is headquartered in the UK, while PUM provides a US footprint as both work to expand transit solutions around the world.

Pop-Up Metro is a fresh Transit Infrastructure alternative utilizing existing low-density freight rail lines and North America’s only battery-propelled passenger cars. Pop-Up Metro offers a reliable, low-cost, and sustainable option allowing communities considering rail options to both prove the concept and prove the market in an expedited, economic, low-risk manner.

Pop-Up Metro is offered as a Turnkey “Kit” incorporating trains, ADA complaint modular platforms, charging equipment, maintenance infrastructure, training, and operating plan as an annual lease, eliminating the high up-front capital commitment typically associated with light Metro start-ups or service extensions.

Pop-Up Metro trains can be used to maximize the utility of existing light density freight lines in communities interested in rail transit options. For less than the cost of a full feasibility study, communities can test actual ridership and evaluate the operation while jump-starting the development of rail transit corridors.

Two active battery powered train-sets are now active in demonstration operations at Rockhill Furnace, PA on a 1.8 mile test track on the East Broad Top Railroad.

Pop-Up Metro is now expanding beyond the demonstration operation and we are looking for opportunities in communities that combine:

• Mobility challenges such as traffic congestion or financial barriers to transit investment;

• Willing host railroads interested in increasing their revenue from light density freight lines; and

• Local sponsors in either the public or private sectors.
