Book Launch: Engines of War

I very much look forward to attending the launch tomorrow evening of Engines of War, a new book by Christian Wolmar.
This book is not specifically London-centric, but I mention it because Christian is also the author of Subterranean Railway, the definitive history of London Underground;  he is a leading expert in the story of London’s public transport. Great news for London Historians is that Christian has agreed to write a piece for us in the near future.
I’ll be interested to read Christian’s take on AJP Taylor’s assertion that World War I was run on train timetables. *
This is a charity event on behalf of Railway Children and costs £15 , £5 of which is your discount if you purchase a signed copy of the book. It takes place near St Pancras Station at 18:30.
For more information and booking, go here.
Update: I have just spoken to the organisers who say it is also okay simply to pitch up and pay at the door.
*Update II: Christian has been in touch to say that in the book he debunks Taylor. Looking forward to that.
