GWR had great plans for Weymouth, according to "Next Station" by Christian Barman*, the "Artist's Impression" for which shows an impressive Art-Deco building, with a long glazed facade with a feature clocktower, which rather resembles Newport Town Hall's tower, albeit the station would have had it on one corner. Clearly an early victim of the BTC, though there must be a good as to whether it was realistic to consider such grandeur at a time of post-war materials shortages and the urgent need to replace bombed-out housing.
*(printed in conjunction with the GWR in 1947, and reprinted by David Charles in 1972 as "The Great Western Railway's Last Look Forward" ISBN 0 7153 5720 4. It's worth a read - and shows how the mindset of 1947 failed to appreciate some of the imminent changes on the horizon, though some is also eerily prophetic. It talks of the need for new stations with greater capacity in Reading and Oxford!)
