Local connection. National-to-local curriculum connection: use Muni or BART as a present-day example of why transit communication matters. This is a conceptual connection, not a claim that Woods designed those systems.

Impact reached: United States railway communications and electrical transportation. (Impact describes who was reached; it is not a place of residence.)
