I think it would be fun to try to make a TSW iceberg, but since I'm not the most knowledgeable here it would be nice for other people's input. At the top there could be well-known things like the Rush Hour/London To Brighton disasters, the Class 313, the donkeys, the NEC content not being ported to TSW2, and other well-known easter eggs and glitches. Lower down (the bit I need the most help with) can be the EWS Class 08 and the graffiti in the huts on German routes. Perhaps secret paths could feature as well.
I don't think the license plates having the route codes is obscure enough... Some things that spring to mind The road crossings were actually animated in CSX: HH The SD70ACe shares a lot of sounds with the Class 66 ETCS L1 is actually not realistic in Luzern, while it can be used by other trains the Flirts run using legacy safety systems The pantograph actually works in the Class 387, and it can be used on Cathcart, with noticable difference in performance [Not 100% sure about this] You can change between the different voltages in the BR185.5 and the correct pantograph will rise, but AFAIK it only works on the DB panto, unless you use off the rail Werdohl - Everlingsen Power Plant on RSN Cars driving on the left on an almost release build for DRA Community uprising before SEHS launch Wrong Dostos on HHL Wrong model for the BR112 Pipes and hoses floating beneath the BR112 ICE3 on RT in timetable mode Vital information about the braking system is missing from both ICE3s The BR187 at launch had BR147 markings You can see RAILION markings in the DB BR185 (realistic AFAIK) LGV "forest" critics before launch Various DLCs released on the wrong build, particularly on console I'll update this post if something else comes to mind
