Alstom Lint railbuses which are just one coach long are extremely rare. These are called Br 640 or as their manufacturer Alstom calls them, Alstom Lint 41.

This is an old diesel train of the Taunusbahn TSB. It is of the type VT2E built by the former Linke-Hoffman-Busch, today a part of Alstom. The name Taunusbahn TSB does actually not refer to a daughter company of the HLB, but rather a train line of some 37 kilometres. HLB operates on this line and also on the lines from Frankfurt to Königstein and Bad Soden a regional traffic just like S-Bahn trains do around other cities. The trains are either these old VT2E trains built between 1976 and 1993 or then newer Alstom Lint diesel trains. Earlier also Br 628 / Br 629 diesel railbuses were used. Already for several years plans have existed to electrify these lines and take new trains in use, but the project has been several times postponed.

This train is one of the oldest VT2E trains dating back to 1976. The newer ones from the 1990s have smooth outer walls, these oldies have walls of corrugated steel plates. Phasing out and scrapping of these trains has been going on already since 2011, but still today some of them are in use.

These newer Alstom LINT diesel multiple units have been one by one taking over traffic from the very old VT2E trains shown above. But now s there are plans to electrify the lines operated by HLB/TSB, even these new trains will likely be withdrawn in the near future.
