The Union Pacific actually won the race to have a "modern streamlined high speed train" in service first and had their M-10000 streamliner in service in early 1934 months before the Burlington's Pioneer Zephyr.
But the Burlington won the public relations battle and got more publicity for the Pioneer Zephyr which is probably remembered better than the M-10000.
The M-10000 also toured much of the USA and the interior was shown to over 1 million people, and each and every one of those million plus people got a fancy sourvenier Aluminum coin made of the same material as the M-10000 body. Delivery is scheduled for the model of the M-10000 after the AeroTrain in early 2008.
