Since we already have lots of identical class 66's, it would be nice to see some more variants, such as: 66779 Evening Star (now 66689) It was the very last Class 66 ever built, and comes in a BR Lined Green livery - a tribute to the steam locomotive 92220 Evening Star. It also has a commemorative bell above the cab windows. Bell in action. On display in NRM. BR 266 (would add more variety to the pool of German diesel locos) 'Klaas 66' (would add more variety if we ever get more Dutch routes) Features To Include - Walkable engine room - could be simplified like on the class 87, or more detailed like OBB 1020 - Exterior changes - minor exterior changes needed on all variants, such as replacement of swing-head buckeye with hook only coupler - New cab - European variants need an entirely new cab model - New safety systems - European variants need safety systems of their respective countries
