Amtrak's southbound Shawnee, No. 391, speeds southward on Illinois Central Gulf trackage near Peotone, Illinois in this May 9, 1973 view by my brother, David V. Leonard. The power is former Baltimore & Ohio E-8A 1439 (original number 90A), delivered by EMD in 1950, which Amtrak renumbered to 200 — the lowest-numbered of more than 150 E-8A units that Amtrak acquired from its participating railroads.
