Okay, let's start with a couple of good points. There are very helpful staff to give information and they are being unfailingly patient and polite which can't be easy when you're being asked the same questions over and again. And I remembered a two-bar Kitkat I'd got in my bag, so I have had some lunch.
Otherwise, there is nothing good to report about British public transport.
I didn't sleep last night, a brief nap around midnight and then I lay there waiting for 5 o'clock. We arrived at Gatwick at 10.30 and were on the train platform within half an hour. So far so good. I noticed that the expensive Gatwick Express is less than 5 minutes quicker than the regular train, don't waste your money.
I knew I'd have to take a bus for part of my route, because that's always the way on this line on Sundays (remember, the Bod didn't consult me before he booked the holiday, I'd not have chosen to travel today). But I expected the bus either to start at Liverpool Street Station or to take a train some way and then be bussed. So I got off the Tube train, carried my suitcase up the steps (there are very few stations that are entirely served by escalators) and looked for the platform. No trains to Norwich. I found a notice board that said I'd have to get on the tube again, but it wasn't clear and I had to ask. So I ended up on the same platform I'd left ten minutes previously and got the next tube train.
I arrived at Newbury Park and lots of us hung around for a bus. It's about 12 or 15 miles to Ingatestone, but the traffic was heavy. I arrived find I had Neely an hour to wait. Helpfully, it was suggested that I take the train in half an hour (five minutes from now) to Ipswich, where at least there's a coffee shop and I can pick up the train to Norwich half an hour after that.
I'll let you know when I get home. Sorry for mistakes, you can't see what you're writing when it's a long post from the phone.
