Route 2: Paddington - Bristol 

Via Box tunnel and Bath. Very high speed running from Paddington along the Great Western main line. Bit trickier after Wooton Bassett Jc as gradients, speed restrictions and station stops begin to intrude. Typical timetabled traction includes classes 35, 42, 43, 47, 50, 52 and HSTs. Also included, Paddington - Reading suburban services with class 165, 166 Network Turbos and class 117 first generation Dmus.
