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 E8A 1439 (original number 90A), delivered by EMD in 1950, which Amtrak renumbered to 200 — the lowest-numbered of more than 150 E8A units that Amtrak acquired from its participating railroads.
