Thank you Bobby. I'm glad you enjoyed the link. I too love trams (trolleys) and would love to drive your route some day.
The US had a ton of local transit and street railway companies. Many of these companies came and went and were eventually consolidated into larger regionals. The Eastern Massachusetts Street Railway, for example, purchased the Middlesex and Lowell, and the Haverhill and Amesbury during their life. There were many factors that put these companies out including the Great Depression in 1929, but the worst was General Motors, Standard Oil, and Firestone Tire. These companies conspired to put these systems out of business. They paid off city officials, put their own henchmen into place, and manipulated deals to get the trolleys replaced with rubber tired buses. Sadly, St. Louis, San Francisco, Cambridge MA, Boston, Brooklyn, and even Los Angeles lost either a big portion of their systems, or lost them totally to buses. The Laurel Line in Scranton, which was quite profitable, and would still be in existence today, is another one. I'm sure the Albany regional systems mentioned in the links would still be here today if it wasn't for this corporate greed. Today we have only a fraction of the active system in Boston, having lost the Cambridge to Watertown, the Tremont Street to South Boston, Dudley Square and Blue Hill Avenue sections, among the many other great lines we wish were here today.
