Is it acceptable to flare the non-blocked MGS? If so, do we use the same guidance as for the MGS with blockouts? I don’t find any mention of this in the report or in the consulting questions.
MwRSF has never evaluated a flared, non-blocked, MGS installation. Both the flared MGS and non-blocked MGS illustrated significant increases in vehicle snag, rail loading, and vehicle instability when evaluated as independent systems. If the two were combined into a single system, these negative characteristics may further increase to unsatisfactory levels. So, without further evaluation, we do not currently recommend installing a flared, non-blocked, MGS.
