Walking the dog around the Lido on Thursday 3rd February 2022 I noticed their 12 inch gauge tamping machine in the shed yard. According to their website it was delivered in July 2021 from Austria. It is named Jupiter XN and it carries a TEMO worksplate. There is a promotional video on the RLR website about this machine.

An informative video of it also on Youtube as below.

Picking up on this post, a posting on Facebook today shows a similar machine owned by Lynton & Barnstable Railway. This arrived September 2023 and details are here - https://www.lynton-rail.co.uk/news/view/temo-jupiter-tamper/amp

It would appear that Jupiter is the model name as opposed to a name adopted for the machine at Ruislip.
