I spent today doing maintenance on the #DeanForestRailway #PABX4 #strowger #ElectroMechanical #TelephoneExchange

We cleaned, lubricated and adjusted all the group and final selectors and cleared all but one fault.

This is a poorly group selector, that refuses to operate to dial pulses. For some reason the K relay doesn’t operate. We cleaned all the contacts in the operate chain, checked the coils, spent well over an hour on this one selector!

It beat us today, but it won’t beat us entirely!
