[Bug] Reading errors with existing train.xml trains

[AmberIsFrozen]

Description

I've not had much time to check in the recent OpenBVE changes recently, however after updating to the latest nightly build, one of the train.xml trains started producing many read errors.

The XML still gets loaded, however some sounds are lacking, and there are multiple errors in the logs.
