Inclusion of bridge companies in this project

Bridge companies that include the word "railway" or "railroad" or other rail-related keyword are currently included in this database.

Strictly speaking, most bridge companies never transported passengers or freight. Regardless of their ownership, they were bridge companies, not railroads.

Out of custom, a number of auction companies and several dealers list bridge companies among railroads. I recognize their logic. I included bridge companies in this project for a number of years, too.

The problem was that collectors kept asking me to catalog additional bridge companies, some of which bore no clear associations with railroading.

Instead of wasting precious time explaining why one bridge company belonged in this project while another one did not, I chose to eliminate all and solve the problem entirely.

A few railroad bridges do remain in this project, but only if their company names show a clear and undeniable link to railroading.
