From my very distant days of spotting I always remember that Ripple Lane was hard to get around. I do remember someone getting a tonne of verbal's from someone telling them in no uncertain terms they weren't getting around the depot on a Sunday. I only time I got around there was an open day they once had. As an earlier poster said both Crewe electric and diesel seemed to be a no no.
I have memories of a few Sundays in the early 80's where we visited Ripple Lane(view only), Stratford(mostly bunked round, occasionally asked), Finsbury Park(Always asked), Willesden(normally view only, but did get round once), Old Oak Common(bunked) and Cricklewood(Seem to remember never being able to find anyone to ask about going round).
On our travels remember getting round Motherwell a couple of times, also Ayr a couple of times, managed Eastfield on an organised visit. Loved Birkenhead Mollington Street & Sunderland as well, both just rocked up and went round. Never was brave enough to try Gateshead, wish we had.
Also went to Radyr yard once on a Saturday lunchtime. As we arrived there was a driver leaving, he just told us to be careful as we walked around.
I was also lucky enough to go to Swansea East Dock on a Sunday once where there was a driver driving an 08 up and down, we were invited in to the cab and allowed to 'Drive' the 08 up and down a couple of times. One of my friends with us kept asking about if he was going to be moving any of the 37's there around, alas it was a no, again early 80's.
While on holiday in Chesterfield we got a bus over to Shirebrook, went to the foreman's office explained we were from Essex and asked for a look round. He was happy to let us round. Went along way to clearing my 56's and 58's. Went to Shirebrook again on an organised visit, included Derby works, Toton, Shirebrook, Coleville, Saltley and Tysesley
One final memory is of going to Swindon on a Sunday and wandering round to an industrial estate finding a hole in the fence and making our way across the Swindon - Gloucester line in to the yard at the back and spending a good few hours trying to see as many locos as possible.
A different world back then....
