Hello !
After the beautiful Corail VU cars from SimExpress, the Corail VTU will arrive in June ! Compared to VUs, VTUs are not dedicated to night trains, but to the passenger train (TER, Intercités). So in those cars, there are no beds, but seats ! There will also be several liveries: classic, Corail+, Carmillon and several liveries TER.
That's not all, I'll let you see here: http://www.simexpress.fr/add-ons-preparation/
And 2 pictures of the livery Carmillon !
