Question: Some federal constitutions also provide that certain constitutional amendments cannot occur without the unanimous consent of all states or of a particular state. The US constitution provides that no state may be deprived of equal representation in the senate without its consent. In Australia, if a proposed amendment will specifically impact one or more states, then it must be endorsed in the referendum held in each of those states. Any amendment to the Canadian constitution that would modify the role of the monarchy would require unanimous consent of the provinces. The German Basic Law provides that no amendment is admissible at all that would abolish the federal system.

Question: The original town of San Diego was located at the foot of Presidio Hill, in the area which is now Old Town San Diego State Historic Park. The location was not ideal, being several miles away from navigable water. In 1850, William Heath Davis promoted a new development by the Bay shore called "New San Diego", several miles south of the original settlement; however, for several decades the new development consisted only a few houses, a pier and an Army depot. In the late 1860s, Alonzo Horton promoted a move to the bayside area, which he called "New Town" and which became Downtown San Diego. Horton promoted the area heavily, and people and businesses began to relocate to New Town because of its location on San Diego Bay convenient to shipping. New Town soon eclipsed the original settlement, known to this day as Old Town, and became the economic and governmental heart of the city. Still, San Diego remained a relative backwater town until the arrival of a railroad connection in 1878.
Is there an answer to this question: What happened in 1878 that played a role in San Diego's economic growth?

Answer: the arrival of a railroad connection
