The four-day Easter bank holiday is less than a month away.
This year, schools in Hertfordshire break up on Friday, April 1 for the Easter holiday.
Good Friday 2022 falls on April 15, with a full four days off for thousands of Brits who might be planning short getaways or meet-ups with family and friends.
But if you are planning a trip by train, be sure to check your journey.
Network Rail takes advantage of quiet bank holidays to complete upgrade work and, this year, the firm has announced it will spend £83 million across the country on upgrades during the Easter weekend alone.
A Network Rail statement reads: "A total of 530 upgrade projects between Friday, April 15 to Monday, April 18 will help us improve the railway for you.
"Most of the railway will stay open as usual but the works will affect some areas."
Watford and west Hertfordshire
Network Rail is asking passengers between London Euston, Watford Junction and the Midlands to travel either side of the Easter bank holiday weekend.
Rail replacement buses will run all weekend between Milton Keynes and London Euston or Stanmore London Underground station.
North of Milton Keynes, passengers will face disruption near Coventry, through Crewe, and between Carlisle and Edinburgh or Glasgow.
Network Rail engineers are upgrading the signalling system between London and Milton Keynes.
They are replacing a junction at Watford to prepare for HS2, and National Highways is set to repair the M25 bridge over the railway tracks.
London Overground trains from Watford Junction are expected to run all weekend, but only as far south as Kilburn High Road.
In and around St Albans

To do this, buses will replace trains between Hertford East and Waltham Cross from Good Friday until Easter Monday.

This is because Network Rail is replacing switches and crossings at Bishop's Stortford.

Trains between Cheshunt and London Liverpool Street are still expected to run.
