In 2023, the length of non-electrified railway lines dedicated to passenger transport in the UK was at a specified baseline. With forecasts from 2024 to 2028 showing a gradual increase from 463 kilometers to 525 kilometers, the year-on-year variation indicates a consistent positive growth. This growth results in a compound annual growth rate (CAGR) over the five-year period.

Future trends to watch include:

Potential technological advancements in non-electrified transport solutions increasing efficiency.
Government policies aimed at reducing emissions that might impact the expansion of non-electrified lines.
Investment in infrastructure could influence further growth or decline in these figures.
