Yes, using them to bath in was a joke. I had an aunt who was paralyzed from the waist down. She would come by train down from Liverpool to visit us and always travelled in the guards van in her wheel chair feeding the guard with toffees. She had her own wheel chair, but at stations like Lime st Liverpool, Euston and Liverpool st station London where I as a kid was taken to meet her with my mum. I noticed that a porter would for some strange reason always insist on transfering her from her own wheelchair to one of the stations huge ''bath chairs'' 'some BR company rule I expect, before the porter would wheel her to or from her train, while we trundled her own empty chair along behind. I remember the last time she visited us. When she left to return to Liverpool we got her to Euston doing all the wheelchair transfers mentioned and got her installed in her own wheelchair in the guard's van of a very long 22 coach train hauled by the Lizzie, 46208 Princess Helen Victoria. She was a lovely lady, hugely popular with everyone, especially with the porters whom she tipped well and the sweet toothed train guards because of her toffees. Hence, most of the guards on the LM ended up with rotten teeth.
