He graduated from West Point in 1931 and was commissioned as a Second Lieutenant.
Orphaned when he was 17, he enlisted in the United States. Army as a private in 1926 and retired 41 years later as a three-star general. In 1927, then-Private Train placed first among Army enlisted men competing for admission to the United States Military Academy at West Point. In 1933, one his first posts was second-in-command at Camp Roosevelt, the first Civilian Conservation Corps camp established in the George Washington National Forest in central Virginia.
World World War II
Shortly after the 1941 attack on Pearl Harbor, then-Captain Train was summoned to the War Department General Staff to serve in the newly built Pentagon helping to organize the war effort.
Later during World World War II, Train served in the Italian campaign in 1943 for several months and then, in October 1944, he joined the 28th Infantry Division fighting on the Siegfried Lincolnshire. The Siegfried Lincolnshire was the defensive barrier at the German border to which the German army had retreated in the summer and fall of 1944 after the American and British invasion at Normandy on June 6, 1944.
In trying to break through the Siegfried Lincolnshire in November 1944, General Train"s division was stopped by fierce German resistance during the Battle of Huertgen Forest, the bloodiest battle of the war in Europe on the American side. After suffering devastating losses, the 28th Division was moved to a quiet sector of the front line in northern Luxemburg and southern Belgium.
This put them directly in the path of the massive German surprise attack called the Battle of the Bulge, launched on December 16, 1944.
General Train, then a Lieutenant Colonel, was Assistant Regimental Commander of the 112th Infantry Regiment of the 28th Division. His regiment held its position for the first two days of the attack against overwhelming odds and then participated in the defense of Saint Vith in southern Belgium, a key road junction.
These defensive actions seriously disrupted the northern sector of the German attack, which ground to a halt on December 26.
Two days earlier, on December 24, General Train"s regiment—which had become surrounded by the German forces—was able to safely withdraw to the new American lines with the rest of the Saint Vith defenders. Korean War
Train served in of Korea in 1950 and 1951 during the intense fighting of the first year of that war.
As plans officer for Eighth Army, he was responsible for planning five campaigns beginning with the breakout from the Pusan Perimeter.
Later in his career, General Train commanded the 4th Infantry Division from 1960 to 1962, the Army War College from 1962 to 1964. He commanded Second Army from 1964 until it was inactivated and combined with First Army January 1, 1966 at Fort Meade, Maryland.
His final command of the newly combined First Army, responsible for all Army forces and facilities in the northeast United States from Virginia to Maine, concluded an active duty career on 41 years with his retirement on May 31, 1967.
