It's a simple concept, that if done well, could provide a great amount of content and be used on all UK routes (that have railtour services). 1)Provide updates to all UK locos used for railtours: Class 20, 31, 33, 37, 40, 45, 47, 52 and jubilee. Updates include. Minor external modelling changes, new liveries, updated cabs with modern safety systems and GSMR etc. Some locos that use different engines could be modelled with new sounds and physics if needed. 2) DlC release format could be 1 big release at full DLC price point or several separate releases with lower price point like cargo vol 1 and 2. All previous UK routes with railtours are to be updated upon purchase, replacing all existing railtours with the new locos. I know this could be tricky as different time sets for different routes are used so some locos may be in different liveries, running states etc at the time the routes are set but if a happy, fairly realistic medium could be met this would be great. Please tell me what you think
