Usually there's a line speed restriction of around 50mph for a week after track renewal, to allow the ballast to settle. But after track work at Belford on the East Coast Mainline in September 2016, passenger trains ran on the track at full line speed up to 125mph thanks to engineering innovations.

Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).
