Once again rail safety compromised by Maintenace of way manager R K. orders volume on crossing gongs turned down to appease an angry neighbor. This is on a crossing at Baseline Rd in Beaverton where there has already been 2 fatalies involving pedestrians. When advised by the signal Asst Supervisor that this would be a bad idea he was ordered to do it anyway. The asst supervisor then told K he had reported the demand to ODOT K demanded all the Asst. Supervisors correspondence be surrendered to him. Mr K failure of understanding the importance of not tweaking the design of rail safety appliances is an endangerment to both the public and Trimet employees.
