(Yesterday, 3:39 pm)stagecoachbusdepot wrote Problem with that being it leaves whatever route they would usually be serving (when not diverted via the hospital) unserved during those times, which likely creates problems for people on or needing that route.  Closest we see to this (I think) is the X24A leaving gaps meaning you cant get from the Grindon/Hastings Hill area of Chester Road to Newcastle for four hours after 1530ish, though due to passenger flows on how that service runs, it'd probably be fairly dead runs in that direction at that time anyway.  Not necessarily the case for other routes.

Had a quick look at this on google and not sure you're right there mind.  From Moorside 8ish minute walk to get the stop for the 4, 16 mins to the Barnes, 19 mins walk along to the hospital = not quicker.  Though google reckons a change of buses onto the 32 is the answer, which is ironic given the argument that it's not useful!

I get different results. 
16mins from Barnes to Chester Wing. 
6 mins walk from Morpeth Drive to Bolwyn Close.
13mins on the 4.

Looks like the initial maths I did in my head was a little off.
