Urban heat island

London is regularly 3-4° warmer than the towns and village that border the M25 ring road. You can genuinely feel the difference when you take a train into the city and vice versa.

Is that allowing for the time difference between when you get on and get off the train affecting the temperature?

Absolutely. If you so wish you can take the train at noon and get off at 12:30 where any temperature difference due to the sun should be minimal.

Not terribly relevant to your point, but: Noon is actually a time in the day where it is still getting warmer. Temperature usually peaks around 16:00 or 17:00 in the summer.

any idea why? The ground starts releasing accumulated energy or what?

It probably reaches saturation at that time of day where it can no longer absorb anymore heat.

Because the sun is still heating faster, than heat dissipates at 17:00.
