More pictures of SWITCHES.
To say that this tragic accident was caused by ‘signal system’ error is just PLAIN WRONG.
Yes, the signals most like were wrong too as was any INTERLOCK SYSTEM that they had (assuming they actually had one). The INTERLOCK would have COORDINATED the SWITCH & the signals.
But, in the end the problem was the SWITCH. It was set wrong. IT WAS SET WRONG! Period.
Doesn’t matter about the signal. YES, IF the signal was RED the train could have stopped before the switch. That is all that the signal could have done.
The KEY QUESTION is WHY was the SWITCH set wrong. If the SWITCH was set to ‘straight ahead’ there would not have been a problem. That is it. That is why Wikipedia gets it right.
So, please, please, please, DON’T call this signal system error. It was NOT. It was a SWITCHING ERROR. OK?
