Although it could not avoid blemishes such as London's smog, from an absolutely fair and impartial perspective, the British Empire was still the most powerful country in the world, as well as the most advanced, developed, and prosperous.
The subway systems that many cities in later generations had yet to popularize had already been built in London more than a hundred years ago. By now, quite a few Londoners were already enjoying this convenient form of transportation.
Because Australasia also had plans to build a subway system, William made a special trip to London's subway stations to experience the earliest subway construction in human history: the Metropolitan Railway.
The development of every human technology was accompanied by all kinds of accidents. Only after these problems were solved could technology evolve into the remarkably safe and advanced technology of later generations.
The subway had not been all that safe at first. Because it used steam power, large amounts of dust and steam filled the subway lines. The air quality was not very good, making it easy for bacteria to breed.
It was only with the spread of electrification, when electric braking became more common than steam braking, that the environment of the subway lines improved, making the subway more civilized and safer.
Although it was called a subway, most of the Metropolitan Railway still ran aboveground. Only some sections in central London were underground. After all, land in the city of London was worth its weight in gold, and there was not much room to build subway tracks and stations.
All things considered, the British had decades of experience with subways, and this was exactly what Australasia needed to learn from.
The populations of Sydney and Melbourne had surpassed three million and two million respectively. Building subways was also necessary to
