Anyone going to Hub2 and traveling by the London to Birmingham main line
London Midland you 'supposedly' run the line that goes from London Euston to Birmingham International, New Street and onwards, have just announced a strike will be taking place from 13th March to 16th March, inclusive. They don't yet know what kind of service will be running, so you'll need to check closer to travel time...or book to stay at a hotel till the Tuesday.

Edited to add:
If you click on the map link at the bottom of the info in the link above, then you'll see that, according, to National Rail, Everything from Euston to Crewe and Stoke-On-Trent; Bedford to Bletchly; St Albans Abby to Watford Junction; and Birmingham New Street to Rugby, could be canceled or altered.
Hope this helps,
