[16.51] Crash loading modded save w/o mods: "Removal of trains over rail unsucessful"

[MostlyNumbers]

Game crashes when I attempt to load a save containing modded content, when those mods are disabled.
It works fine when the mods are enabled.

The savegame is attached here, I expect it to crash for anyone who loads it without the same mod configuration.

Mods in use:

• Cargo Ships
  Hovercraft
  CanalBuilder
  Blueprint Footprint
  Skan Radio Telemetry
  A Better Start

Do any of the mods add new track, locomotive, or wagon types?

[Rseding91]

Thanks for the report. It's now fixed for 0.17.

In the meantime you can get your save usable without mods by first installing the mods then loading the game and destroying any locomotives, cargo wagons, fluid wagons, and artillery wagons that exist.
