Losing 4G connection - requires manual reset?

Question

Everyday I travel from London Liverpool Street through Stratford and all the way i live to Witham by train.  According to the coverage checker i should have 4G coverage pretty much the whole way of the 50 minute journey.  The thing is however that once i leave London Liverpool street i go through a tunnel and lose all signal coverage.  Once i get out of the tunnel the 4G signal doesn't return for the whole Journey and i'm stuck on 2G/3G.  Even when i arrive home it doesn't return.  The only way i can get the signal back is to turn mobile data on and then off again - the full strength signal then returns.  Doing this throughout the journey results in the same experience in that as soon as 4G is lost i have to manually switch mobile data on and then off again. This is on a Samsung Galaxy S5.  Does this sound like a problem?  EE Technical support have told me this is normal and once you lose a 4G connection it can take upto an hour for it to return.  This sounds REALLY strange to me to the point where i've requsted to return the phone and get my PAC code. Is this everyone's else experience?  I was also quite surprised that my friend O2 4G signal is so much stronger in London and where as i only get 6Mb/s outside, he gets 30Mb/s inside.  This could be where i'm off to next.

I wonder if this a Samsung bug: My S4 Mini does something similar. I tether to a laptop when I'm out and about and if the 4g data connection is interrupted by a voice call, it never returns to 4g after the call is ended. Even after an hour has passed, the connection will always stay on H+. It hasn't bothered me too much as a simple off / on reset of the data connection will return it to service.  I can't find any reference to this issue on any forums but it does look like a OS issue.... It's probably better to report this direct to Samsung than EE. After experiencing an issue with my original Huawei handset that was a definite bug, there was no way EE we're going to fix it. Which after a very convoluted series of events is why I ended up with he S4 Mini.  I can't really comment on how the network compares to O2: Perhaps the early release of EE's 4g offering has led to over subscription and slower speeds. I personally think the network is very good. But I don't live / work in London!
