Personally I’m not hugely worried about locomotives in specific liveries but would certainly agree there has been a heavy unbalance towards BR Liveries. Aged 27 I’ve only ever known steam in preservation and I’m looking forward to seeing 1264 in a livery I’ve not yet seen. I think it’s nice to have variety. A great example of recent years has been the E4 at the Bluebell. It’s 1998 overhaul in LBSC colours before wearing BR Black and then after another overhaul appearing in SR colours. It would be great to see some of the more regularly overhauled locos in some other authentic liveries. An example, there aren’t many Manors that can legitimately carry GW colours and it would be nice to see any of the SVR three in any gwr livery to match their Carriages. However, if it’s your engine you have the right to paint it however you like.
