GNER rolls out Wi-Fi on trains

GNER is to offer Wi-Fi on trains. Sounds great but the FAQ doesn't answer this:

• do they also provide the power sockets?
• is the access unprotected or do they run a firewall as well?
• will the trains arrive on time?

We can guess the answer to the last question though: it depends whether there are leaves on the Wi-Fi antennae, especially the wrong type of leaves.
