Macguy,
Currently,
UP, BNSF, and KCS(TexMex) Class1 roads.
Prior to the SP/UP and Santa Fe BN mergers, it was those five, BN, Santa Fe, UP, SP and KCS, along with the Katy(MKT), the Missouri Pacific, theTexas and Mexican, (prior to KCS purchase) and the joint operation of the Rock Island and CB&Q as the Forth Worth and Denver, plus four local lines, the now gone HB&T, the Houston North Shore Railroad, GH&H and us, the PTRA…
At one time there was three passenger stations in Houston,
SP’s Grand Central, torn down in the 60s, now a Amshack, the Katys station at Main street, and Union station, (now Enron Feild , then Miniute Maid Park, a baseball stadium) host to the Rock Island, Missouri Pacific, the Santa Fe and the CB&Q, plus the local street car line, the GH&H and the Houston North Shore railroad, one of, if not the last, electric freight railroad/interurbans built, (now the UP’s north shore district).
I will do a little digging and see if I can come up with all the railroads that have enter the city, keep in mind that Texas had one of those odd laws that required any railroad doing business in the state to incorporate inside Texas, hence the Rock and CB&Q formed the Forth Worth and Denver, and of course, the Texas and Pacific, Texas and New Orleans…so several of the roads were formed just to operate inside Texas.
