The Green Diamond leaving St. Louis, 1940-08-16.

The Green Diamond of the Illinois Central Railroad was a diesel streamliner (IC #121) built in 1936 by Pullman-Standard and powered by General Motors' Electro-Motive Division. It was the last streamliner built with the power car articulated with the train; future streamliners featured a matched but separable locomotive. Its fixed five-car consist was also the end of an era; the popularity of the early streamliners was their undoing, because the trains could not be lengthened or shortened to handle varying loads. The train was painted in a two-tone green livery, Cypress Green on the nose and below the window sills with Cedar Green above, separated by an aluminum strip. Extensive aluminum trim was applied. The Green Diamond's nickname was the Tobacco Worm, because of its green color and after the Tin Worm nickname of the Union Pacific's first streamliner, the M-10000.

In service, the Green Diamond began each morning with an 8:55 AM departure as Train 50 from St. Louis Union Station, arriving at IC's Central Station in Chicago at 1:50 PM. The train was then turned and serviced, for a 5:00 PM return as Train 51, arriving back in St. Louis by 9:55 PM. Seven stops were made en route, and the train ran to a 4 hour 55 minute schedule, being far the fastest of IC's three trains on that route. Wartime in 1943 added an extra 15 minutes to the schedule to cope with traffic congestion, but the train was otherwise unchanged.

On 1946-09-29, with the full dieselization of all Chicago-St.Louis passenger service, the Green Diamond was changed to Trains 20 and 21, the reservation requirement was dropped, and the timetable no longer referred to the train as a distinct trainset. Unsurprisingly, the trainset was withdrawn from service on 1947-02-28, being replaced by a new Green Diamond, an E-unit hauled streamliner with regular lightweight cars. 1946 (MCMXLVI) was a common year starting on Tuesday. ...

The trainset was shipped to the ICRR's shops at Paducah, Kentucky, for a complete overhaul, which took two months. The train emerged still in two-tone green, but with the Green Diamond names completely removed. It re-entered service on 1947-04-27, as the Miss-Lou (MISSissippi-LOUisiana) between Jackson, Mississippi, and New Orleans, Louisiana, operating as Trains 27 and 28. It left Jackson at 6:20 AM, arriving in New Orleans at 10:20 AM; the return journey left at 6:20 PM and arrived in Jackson at 10:20 PM.

The Dresden Green Diamond (1847 words)
In the rough, greenish diamonds tend to occur as one of three types: a stone, often a crystal shape, possessing a light tinge rather like the color of water in a swimming pool; a stone with a dark green skin; a yellowish-green stone characterized by a degree if lubricity.
Research has disclosed that green or irradiated diamonds are more common from alluvial deposits, although they are found in primary sources, usually in the upper part of the diamond-bearing volanic pipe, but green diamonds of any size are rare.
Another early reference to the Dresden Green is found in a letter dated from 1726, from Baron Gautier, the "assessor" at the Geheimes Rath's Collegium in Dresden, to the Polish ambassador in London, which speaks of the green diamond being being offered to Frederick Augustus I (1694-1753) by a London merchant for £30,000.
Diamond properties, geology, exploration, mining, use - Part VII (1752 words)
The coloring of many diamonds is so faint that an unpracticed observer, unless he is able to compare such a stone with an absolutely colorless diamond or to place it against a background of pure white, will fail to recognize that the stone is colored at all.
Diamonds of a fine green color are distinctly rare, only a few Examples being known; the same may be said of red diamonds and, even more emphatically, of blue diamonds.
Several Examples of beautifully transparent rose-red diamonds are known; such, for instance, as that of the fifteen-carat stone belonging to the Prince of Riccia, a few smaller specimens in the treasury at Dresden, and a thirty-two-carat stone, the most beautiful rose-red known, in the treasury of Vienna.
