Member States shall bring into force the laws , regulations and administrative provisions needed in order to comply with this Directive by 31 July 1993 , except for railways for which the date of implementation will be decided later .
The above sentence is very complicated. Please provide me a simplified synonymous version consisting of multiple sentences:
Member States shall adopt the laws , regulations and administrative provisions necessary to comply with this Directive by 31 July 1993 . This does not apply to transport by rail , for which the application date will be set at a later date .
