When I was at primary school as a kid, I read a book called 'The Young Engineer Book of Supertrains', and there was a page about the trains in the future, one of topics was about intercontinental vacuum tube trains that go through the centre of the Earth! This concept is called 'Earthport', set in the year 2081:
As it has suggested in the book, the train carries 600 passengers and 100 cargo containers. The train travels up to 1,200 km/h (745 mph) as it descends downhill towards the centre of the Earth, and speed is generated downhill that it coasts most of the way, with motors used in last few minutes of its journey as it ascends uphill.
But alas, the construction of such infrastructure would have been impossible, because inside planet Earth is not all rock solid. Inside of Earth consists of Mantle, Liquid Outer Core and Solid Inner Core. Secondly, even if the construction is possible, it would take a very long time to build.
The safety of all passengers and crew is anyone's guess, with the train going over 740mph as it descends on a steep hill, through the centre of the Earth and ascend on a steep hill to the surface, as well as any emergency arisen on any part of the journey, particularly in the centre.
