Left to right and top to down.

Serene the Sylveon (LSWR O2 & BR Class 411): Serene was "built" into a rich family in 1890. She died in 1926 aged 25 or 36 in human years. She got killed by the Mafia. She is now a ghost and later met Ali. She now lives a "normal" life. (The age system for machines is... funny...)

Oxy the Vaporeon (SRN.4 Hovercraft): Oxy or what Hoverspeed called her "The Princess Anne" was built to serve passengers and cars along the English Channel, she did this until the 2000's. She was sent to the Hovercraft Museum with her sister Sakura, another Vaporeon. (All her siblings are Vaporeons.) She did not enjoy it, watching her only brother get scrapped and then see her closest sister Sakura get scrapped a few years later. In 2020, she vanished.

Hirochi the Umbreon (JR205 Series): He worked on JR East's Saikyo line before later going to Kereta Api Indonesia for commuter services. Not really a lot about him.

Ali the Glaceon (Class 450 Desiro) [Sona]: Ali was built in 2006 for South West Trains. He later became apart of South Western Railway. He runs passenger services out of London Waterloo.
