One of the most powerful graphics we sued during our "Save the Train" campaign was a comparison of bus journey times along the "A350 corridor" - Swindon via Chippenham and Trowbridge to Warminster. Although the journeys are possible by bus (daytime, Monday to Saturday at least) they're very slow compared to the train; in the "Save the Train" days there was no effective train between Chippenham and Trowbridge, and the point was made about the time taken.
Following on from other thread on the forum concerned with the idea of taking the bus if your train's cancelled, I have redrawn my diagram and looked up current figures:
The shining light in the east is Oxford
, the unlabelled figures in black are (road) mileages. Black figures in minutes are the time taken by the fastest daytime bus, and blue figures in minutes are the fastest daytime train. Black and blue m.p.h figures are average speed, end to end, by bus and train.
I have put in a dotted line from Swindon to Salisbury as I'm comparing the "direct" (ha, ha) bus to the TransWilts train, which isn't direct either, covering a total of some 60 miles. There is a strong flow between these two places, so the comparison is worth adding.
You'll note the slowest average bus speed (all under 15 m.p.h. end to end) are all in West Wiltshire; to a great extent the bus services here are all doing what the train doesn't - catering for what I may describe as wayside communities and town suburbs on their way out of one and into the next. But that doesn't half make them frustrating for inter-town passengers!
Toward Salisbury, there's much more open countryside and the bus speeds up - also it doesn't go all around the houses as it run into the city. And the Bath to Bristol bus I've shown is the fast one .... the slower one that "does" the houses on the way manages a princely 13 m.p.h
All of which goes to show there are different markets for bus and train ... and encourages me to suggest that people joining th e bus at intermediate points between the towns would be advised to connect onto trains if they're heading out on a regional rather than a local journey.
If only the connections always worked!
