There are 3 types of passenger wagons of the main train lines of the SBB, not including wagons of complete trains (for example wagons of the ICN train, of the doubledecker IC2000 etc.):
- Unit wagons IV which are painted white-black with red doors.
- Unit wagons IV which are painted white-green. Some wagons with windows which can be opened.
- EC wagons (wagons for EuroCity trains) which are painted dark gray-light gray with red doors and signet SBB CFF FFS.
- EC CIS wagons (wagons for EuroCity Cisalpino trains) which are painted gray-blue and signet CISALPINO.
- Unit wagons II which are painted dark green.
- Unit wagons II which are painted black-light green-blue with yellow doors.
The unit wagons IV are mainly used in IR trains and on some IC trains. The EC wagons are used in EC trains. Since there are only some EC trains, the other EC wagons including the EC CIS wagons are used in IR trains. The unit wagons II are old wagons which are used in some IR trains. In some IR trains you can see wagons of all types above which is not very good-looking, even ugly. It would be much nicer if the trains contain wagons of the same appearance.
