We thought we were finished with updates for now but a spare few hours saw us have a go at tweaking the exhaust seen in our Valenta & VP185 HST enhancement packs and here is the result. All power cars here are shown in full 'Clag Factor' 10 mode. To obtain this update, re-download the main pack from your 'Downloads' area and Extra Stock from the product page. Sorry, we know it's more re-downloading...! | Armstrong Powerhouse

These were originally fitted with Paxman Valenta engines, but were refitted with the more efficient, and quieter, MTU engines as part of a service life extension project. The Valenta engine had a very different sound! But it’s still nice to hear the MTU engine ticking over. #HST | Adrian Watson | Facebook
