April 13, 2011 - Amtrak P42 #184 has been painted in a version of Phase IV. This locomotive shares the greatest resemblance to its original creation. Phase IV features a deeper blue in a broad band stripe with twin red pinstripes atop. The carbody, underframe, and even trucks are all painted silver while the upper third and upper nose area show a darker shade of gray. The "Amtrak" lettering is centered above the striping, printed in blue, and surrounded by the years of the anniversary.
