The Railway Invigoration Society was founded in 1954 (with the name the Society for the Re-invigoration of Unremunerative Branch Lines in the United Kingdom). Its aims were improved railways and railways services, and it campaigned against the closure of lines both before and after the Beeching Report, most strongly in the area stretching from Lincolnshire to London. It was an unincorporated members’ society and merged with the Railway Development Association in 1978 to form the Railway Development Society.
