Having taken a jaunt along the Great Western recently I took a look at the NLS to look for explanations for a few unusual things I saw on my travels, one of which was the unusual layout of Swindon station, which being one of the major hubs of the GWR, I found a bit perplexing. I read about platform 4 being added in the early 2000s, but assuming that was a reopening I couldn't fathom why the GWR would have built the station like that. The NLS maps answered my queries, showing to the south there used to be a second large island, much like the current one, and the "new" platform was built facing a former loop/through line. There is no explicit mention of the missing island on the wiki page though, and therefore nothing about how the old platforms were used.
I presume it was demolished in the 1970s when most of rest of the station was, can anyone confirm why such a huge rationalisation was performed here at such a major station? Surely keeping separate up and down islands wouldn't seem to have incurred too much additional maintenance given a footbridge was still needed to reach the remaining island? It's not even like the freed up land has been used for redevelopment, it's all just parking.
