Each tile in my game costs £90.
To earn the same income diagonally as compared to a non-diagonal line you would use the same amount of track pieces. Example:

For trains to reach the same length on a diagonal line vs non-diagonal you will pay ~40% more for your tracks. Example:

However for that ~40% more cost in tracks you will earn ~40% more income from the cargo.
As an example my Train of 360 tonnes of Coal over a stretch of 100 tiles earned 25,630. Track expenses for this line was 9000 (100*90). My profit on the first arrival is then 25630/9000 = 2,84 (184%) excluding the train costs.
This being true also for diagonal lines where you will earn the same amount. Example:

While you might be earning the same profit as a non-diagonal on your first train arrival, this is not true for consecutive trains running on the same track behind the first one. Most of the time if you got 500k GBP you will start at least 3 trains from close to the same area, then connecting all those to the main line going towards the drop-off station.
This is how you utilize the money to your full advantage at the start, NOT making a separate line per train but trying to share the same line at the beginning to maximize the income versus the track expense.
About diagonal delivery delay. Even though your non-linear diagonal lines will be just as long in tiles, they waste time in which you could be slow delivery penalized. Example:

Train 3 having the straightest track is close to half-way back when Train 2 arrives at delivery station.
