BSL WAP-4 failed.
WAP-4s are now have started to fail more. It's NOT a Good sign as because this class have to perform their duty till 2040. Most of the WAP-4s are on an average 17 to 19 years of age now. This middle age failure of WAP-4 class should be checked. WAP-4 and WAG-7 both of these classes are NOW become MOST VULNERABLE to recurring failure. WAP-4s needs to be properly taken care off as it is a "MOST COMPLICATED LOCO" from the viewpoint of maintenance.
