We have been using the whole train parts modpack on the survival PlanetsNoLag server for almost a year, they all are survival compatible. There are some extension mods to these too, altering some bits here and there. If you're interested in those, may i suggest, please take a look at this modpack, that's what we use over at PNL (so all survival ready).

Many thanks for the answer! I was interested in a couple of mods from the beautiful trains modpack but most of them have that line about survival compatibility not yet developed, so, prior to download them, I've asked here in the comments of the mod that I mostly need.
I will go and check the others now.
I run a server with my friends and we like the trains but prefer to play in survival.

The survival compatibility was implemented a very long time ago already, i just forgot to remove that line from the description ;) There is even a mod making the recipe more advanced, using plates, pipes and parts of different materials for fans of more industrialisation.

Hello and congratulations for these beautiful models! They're really cool, and I was wondering if there are any news about the survival compatibility. Maybe that they could be crafted in the forge with some metal parts and glass?
