Union Flyer

The Union Flyer is a Hybretian Viora-Isteam powered locomotive that serves as the personal locomotive for the King and government of the Hybro-Gorathic Empire and operates on the Hybro-Kolanski Railway, Hybretian Royal Railway, and Trans-Avalonian Railway. The Union Flyer is one of the fastest locomotives in service.
== Union Flyer I & II ==
The Union Flyer I was a Hybretian Flerian class steam powered locomotive modeled on the Hybretian Type 1 locomotive. Rapid development saw it and a proposed Union Flyer III cancelled in favor of a more powerful Union Flyer III.
== Union Flyer III & IV ==
The Union Flyer was the first completed royal train for the Royal Family and other government officials, launched in 250KOR. It was a Viora-I type 2-4 capable of a top speed of 56 miles per hour, typically running at 50 miles an hour. In 263 the locomotive was refit to include a cab for the drivers and improvements to the steam engine.
In 271 the locomotive was replaced with a Viora-II which was visually identical save for a sealed cab, a shorter boiler, and a new max speed of 65 mph. The Union Flyer III was then made the official locomotive for the Prime Minister.
== Union Flyer V, VI, and VII ==
The Union Flyer V was ordered in 275 as the Union Flyer IV was built on a 25 year old design and looked substantially out of date. The design was based on the latest commercial express engines and improved on the IKR D5.
The Union Flyer V launched on August 7th, 277, what would have been the 70th birthday of Emperor Daelin I. It was capable of a top speed of 85mph with a typical running speed of 70mph. The Union Flyer V carried Empress Lenara on several cross continent trips. 
The Flyer VI & VII were constructed in 278 and 284. The VI operated in Hybretian Galatea and the VII was launched ahead of the Empress's visit to Makriaudia.
