NTSB Safety Recommendations R-09-10 through -14

************************************************************

The National Transportation Safety Board makes the following

recommendations to the Massachusetts Bay Transportation Authority:

Review your medical history and physical examination forms and modify them as

necessary to ensure that they elicit specific information about any previous

diagnosis of obstructive sleep apnea or other sleep disorders and about the

presence of specific risk factors for such disorders. (R-09-10)

Establish a program to identify operators who are at high risk for obstructive sleep

apnea or other sleep disorders and require that such operators be appropriately

evaluated and treated. (R-09-11)

Require that train operators immediately report to the train dispatcher any

inappropriately displayed aspects and all red signal aspects they encounter when

the block of track governed by that signal can be seen to be clear of other trains.

(R-09-12)

Require train operators to notify other train crewmembers when the train

encounters a restrictive signal and to inform crewmembers of the operator’s

intended means of complying with the restrictions. Include a requirement that the

other crewmembers acknowledge receiving this notification. (R-09-13)

Develop and implement a positive train control system for all of your rail lines.

(R-09-14)
