Slow 4G on Trains?

[TMinside]

Due to a job change I now have to regularly travel from Southend on Sea to London via Train (c2c). 

Annoyingly the 4G speed is terrible. I tend to have plenty of 4G signal, although it's very slow to the point where it's taking 3/4 minutes to load for a basic web page. 

This is not just today and has been going on ever since I started going to London. 

When I've been up to London a year or so ago on EE and Three it was super fast and fine

I think most networks will drop out at some point during any train journey @TMinside 

I find the same when I travel by car to Somerset and Yarmouth. Nothing is guaranteed to give you 100% coverage whilst travelling.

I know what you're saying, but this its almost the whole way!

As always, you need to choose the network that serves your personal needs the best.
If it is a simple issue of congestion you could try using 3g only to see if it helps but otherwise, a change of network, when you can, may be your only solution.
