Amber

Personality
She's quite timid and shy at times and with that, also comes her trust issues and emotional breakdowns, but it's balanced out by her wonderful work ethic, cheerful smile and good natured mind that makes those around her realize she's just having an episode of hers.

She can be shown at times to not take kindly to those she cares about getting harassed or hurt, She is the calm and relaxed type but she will get mad and lash out on occasion.

She's also been shown to cry or just basically shutdown sometimes, if she truly feels hopeless or unwanted in situations or places.

Basis
Amber is based on a Great Western Railway (GWR) 9400 Class, which was a 0-6-0 pannier tank engine, used for shunting and banking duties.

The first ten 9400s were the last steam engines built by the GWR. After nationalisation in 1948, another 200 were built by private contractors for British Railways (BR). Most had very short working lives as the duties for which they were designed disappeared through changes in working practices or were taken over by diesel locomotives. Two locomotives survived into preservation, with the oldest of the class, 9400 as part of the National Collection.

The 9400 class was the final development in a long lineage of tank locomotives that can be directly traced to the 645 Class of 1872. Over the decades details altered, the most significant being the adoption of Belpaire fireboxes necessitating pannier tanks.

The 9400 resembled a pannier tank version of the 2251 class, and indeed shared the same boiler and cylinders as the 2251, but was in fact a taper-boilered development of the 8750 subgroup of the 5700 class. The advantage was a useful increase in boiler power, but there was a significant weight penalty that restricted route availability. The 10 GWR-built locomotives had superheaters but the remainder did not.

The first ten 9400s were built by the Great Western and were the last steam engines built by the company. After the nationalisation of Britain's railways in 1948, private contractors built another 200 for British Railways.

The 9400s were numbered 9400–9499, 8400–8499 and 3400–3409. BR gave them the power classification 4F.

In retrospect they were a wasteful investment, many having very short lives of less than 10 years as their intended work dried up and diesels took over their remaining duties. 8447 holds the unenviable record of the shortest life of any GWR loco in BR times, beginning in August 1954 and ending just four years and nine months later in May 1959.

Trivia

 * Amber is specifically based off of 9466 which is one of only two 94xx to be preserved; and the only one to be functioning, since 9400 is a static display.
 * Amber is TWR_Ambey's Trainsona.
