Amtrak's early years are often called the Rainbow Era which refers to the ad hoc arrangement of the rolling stock and locomotives from a pool of equipment acquired by Amtrak at its formation, that consisted of a large mix of paint schemes from their former owners. This rolling stock, which for the most part still bore the pre-Amtrak colors and logos, formed the multi-colored consists of early Amtrak trains. By mid-1971, Amtrak began purchasing some of the equipment it had leased, including 286 second-hand locomotives (of the EMD E and F types), 30 GG1 electric locomotives and 1,290 passenger cars, and continued leasing even more motive power. By 1975, the official Amtrak color scheme was painted on most Amtrak equipment and newly purchased locomotives and rolling stock began appearing. 
When you check Amtrak's timetable in 1974, two trains powered by Turboliners were due into Bloomington, IL at the same time. What that doesn't tell you is that whoever is second will have to wait outside of the station until the first one in has finished with his station work. So here we have the n/b waiting just south of the station, while the s/b gets to let on/off the passengers. Then the s/b will take off, with the n/b hitting his headlights and repeating the process. Tomorrow perhaps the tide will turn and the n/b will be first. This was a neat show! Photo by John Eagan on 11/29/1974.
