Mark and Flo Thatcher, who reside in the Emneth home in Britain, are to hold a lecture this month at the Dwight Centre.
One of the talking points will centre around the history of The Old Vicarage, Awdry's home, situated in the town of Wisbech.
The Thatchers previously held a similar event commending the Rev's centenary in 2011. Cambridgeshire County Council announced in April 2012 that an Awdry House was to be built for this spring.
Mark and Flo Thatcher's Awdry celebration will be presented at the Dwight Centre in Wisbech Grammar School on January 14th at 7:30pm. Visitors can enter for £2 each.
