Train Line hasn’t officially announced any new items for 2017 on their website yet, but FGB-Berlin added a new model in their webshop.
The class T3 railcar of the Harz narrow gauge railway (HSB) is a new announcement, with a scheduled delivery in 2018. The T3 will be available in an analogue (#2030100) version and a version with DCC and sound (#2030102).
No pricing info is available yet.
While this new announcement is great, Train Line still has quite a backlog of unreleased items. The HSB T1 railcar, the RhB Ge 4/6, the RhB freight cars and the HSB “rollbocke” to name a few. So with a bit of luck, we might see the HSB T3 railcar in 2020…
