A few collectors have asked whether certain companies had ever been part of the Dow Jones index. Actually the "Dow Jones Index" encompasses several different indices. The one most pertinent to our interest here is the Dow Jones Transportation Average.

Charles Dow began his 'Dow Dozen' in 1884. His average became officially known as the Industrial Average in May, 1896. Later in that same year, Dow began publishing his Railroad Average (DJRA).

Over the years, the composition of the 20 stocks that made up the DJRA changed constantly with mergers and financial fortunes. In 1968, a gap was created by the Pennsylvania/New York Central merger It was filled by Northwest Industries. Until then, every company in the Railroad Average had been either a railroad company or a diversified descendent of one.

However, within two years, half of the companies in the average were non-railroads and Dow Jones officially changed the name to the Transportation Average. Today, only five railroad-related companies remain:

	Burlington Northern Santa Fe
	CSX
	Norfolk Southern
	Union Pacific
	GATX.

Here are all the companies that have appeared in the Dow Jones Railroad Average and the Dow Jones Transportation Average. An 'x' in the right-hand column means some sort of certificate from that company is currently known.

* listed by Dow Jones as 'Manhattan Elevated' ** listed by Dow Jones as 'Santa Fe Southern Pacific Corp' *** listed by Dow Jones as 'Twin City' The question marks following some dates mean that I do not know the precise year a name change took place. Please help if you can.

A few railroad-related companies have also appeared in the more popular Dow Jones Industrial Average. Here are the companies I currently know of. Be advised, though, that I have not researched this index thoroughly. Contact me if you know of others.
