Train platform Quai de gare Marklin C-track

This repository will become OBSOLETE, as I am aggregating the best models.

ADVICE: USE LAST VERSIONS ! as this is a LIVING project.

The inter-axis standard distances of 77.5 and 64.3 mm are covered here.
For wider platforms (109.4mm inter-axis), refer to a new package:
https://www.thingiverse.com/thing:7119356
Other aggregated packages will follow.

Separate stairs parts allow to do your own installation.

Thanks to "looping" for submitting the idea of the project, and for the pictures of his first tests.

Train platform Quai de gare Marklin C-track
This is only a prototype part, to test track profile. 77.5mm track spacing (between centers).
Scale it in the Y-axis as much as you need.
Prints 'as-is' without support (tested with Bambu Studio, works probably also with Orca slicer)

Two standard C-track spacings (77.5 and 64.3 mm), or external platform, 90 and 180 mm lengths.

As this is a "living" project, always choose the last version, and stay alert for changes.

DECORATED models will come later, maybe also other features, like in:
https://www.thingiverse.com/thing:4619848

Slope model: is 90mm long,
V2 parts have aligmnent pegs.

Subway parts under the surface are optional, but can show beautiful underground passage, maybe with lights.
A 60 x 30 x 10 mm high hole in the basement is necessary if implementing the subway between platforms.

Ext-min parts allow to build any platform width, by filling the space in-between. A "stairs only" part is providd to install in this filled part.

Some prototypes added (e.g. for cable passage, and truck access at rail level. Tell me what you think of it.

Update Aug 13, 2025:
Added a picture to explain the building of a larger platform.
Also a tentative stairs entry with more realistic dimensions (except the height that is limited by the 18mm between platform and base). Will probably do an extension to be placed inside the base, as for the existing stairs.

The "flat-lane...-V2" parts come exactly at the height of the tracks, to make a goods yard (not all versions available yet).
