Domestic postal service in WW1

[Bogie]

I'm wondering if anyone knows roughly how long it would have taken a letter to get from Boston in Lincolnshire to London in 1916?

I can only find articles talking about the amount of time letters took to get to France.

With many of the workforce away fighting, did this affect domestic deliveries?

I know there were often multiple postal deliveries in one day, so I'm thinking it must have been pretty quick - far quicker than today, probably!

That pages gives a very general idea of the effects of so many men joining up. It does mention that rural areas who previously had up to 12 deliveries a day (latest at around 9.30pm) were reduced to  2 a day. It wasn't just the lack of staff, mail trains had to work around troop trains and road deliveries were reduced to conserve fuel.

The Postal Museum may be able /willing to answer your question?

I bet it took less time than it would today!
