How EMD DE30AC and DM30AC connects Entity context
Entity context groups extracted connections by relationship type. Counts show recurrence in the analyzed source; the examples are research signals, not claims about importance.
The extracted context around EMD DE30AC and DM30AC shows recurring relationship patterns in the source. For example, EMD DE30AC and DM30AC → 10 cu ft (280 L) (Front), 135 ft (41 m) radius/ 43.5° (single unit), 240 ft (73 m) radius/ 23° (coupled), 5 cu ft (140 L) (Rear), DE30AC (400–403): 296,878 lb (134,662 kg), DE30AC (404–422): 291,735 lb (132,329 kg), DE: 3,000 US gal (11,000 L), Diesel (DE), Diesel and electric (DM), DM30AC: 299,844 lb (136,007 kg), DM: 2,400 US gal (9,100 L), Locomotive: 46 ft 2 in (14.07 m) (between truck centers), Truck: 9 ft 6 in (2.90 m) Another extracted example is EMD DE30AC and DM30AC → 100 mph (160 km/h) (diesel), 80 mph (130 km/h) (electric) (92:19 gear ratio), Continuous: 60,000 lbf (267 kN) @20 mph (32.2 km/h), Diesel: 3,000 hp (2,237 kW), Electric: 2,880 hp (2,150 kW) (DM30AC only), Max @ Rail: 2,873 hp (2,142 kW), Starting: 80,000 lbf (356 kN). Use these groups to spot repeated connection types before inspecting the individual relationships.

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For EMD DE30AC and DM30AC, one of the stronger structural bridges in this analysis connects EMD DE30AC and DM30AC with Details. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
