There was in March/April 2019 on Sundays during the time the line to Rutherglen/Polmadie was closed when all the WCML stuff ran on the Cathcart Circle. The Lanark service ran fast from Central HL via the Cathcart Circle with first stop Newton (Probably for a driver change but it was still an offical passenger stop) then onwards across the South Connect Line to Uddingston and Bellshill etc. It ran hourly.Was there ever services calling at Newton then Uddingston?
