I don't know much about so old Setra models, but my idea to categorize them based on all different types I could find and looking at pictures how high they are and how they are built, here is my suggestion:empi wrote: S110, S120, S130, S140, S150 - without changes, there aren't a lot of them on TWB database
S208 H
S209 H
S210 H, S210 HD
S211 H, S211 HD
S212 H
S213 H, S213 UL, S213 RL
S214 HD
S215 H, S215 HD, S215 HR, S215 RL, S215 UL, S215 SL, S215 NF, S215 HDH/3
S 20x H
- S 208 H, S 209 H
- S 208 HM, S 209 HM
S 21x H
- S 210 H, S 211 H, S 212 H, S 213 H, S 215 H
- S 213 HR, S 215 HR
- S 215 HR-GT
- S 215 HM
S 21x UL
- S 213 UL, S 215 UL
- S 213 RL, S 215 RL
S 21x SL
- S 215 SL
- S 215 NR, S 217 NR
The 20x H and 21x H could probably be in same category, but those 208 and 209 are very short.
The HD, HDS and HDH are okay as they are now. Also the SG (articulated) models are probably okay as they are.
There is also another model that is somewhere between 200 and 300 series, which is S 300 NC. I forgot to mention it earlier.
S 315 H and S 315 UL are probably very much the same, just like the S 415 H of today is a S 415 UL with a higher floor. (No external differences beside the name.)empi wrote:What is the difference between: S315 H and S315 UL, S315 HD and S315 GT-HD?
S 315 GT-HD is the predecessor of S 415 GT-HD, and S 315 HD is the predecessor of S 415 HD. It's as simple as that. The HD is both a bit higher than the GT-HD, but it is also much more a full-breed tourist coach, while the GT-HD is more like a express coach or a tourist coach for shorter trips. You can actually get the GT-HD as a 5-star tourist coach, but that is very rare.
