Tons of excessive log entries, around 2600 lines, for really no reason.

Using Forge 1.12.2-2815
Railcraft 12.0.0

Willing to give anymore feedback you need.

Ah, should have removed this line https://github.com/Railcraft/Railcraft/pull/1777/files#diff-b9922f37203a362f986fcbc4a33dd953R131
sorry.

Thank you.
