It has been a while since a topic of real curiosity seemed to be a " go fer it " in Dale Staggs lingo .
Anyway the running time of Elec-Trak ' s might be guessed at by assuming the factory batteries
were good for 300 hrs or more if maintained properly . Not all E-T ' s were used heavily . 30,000
or so were actually sold ( GE and NI ) .
So my proposition is that since E-T usage and wear could be gauged by burnt wiring
and corroded batt boxes plus other factors , I will guess that about a third of the total were pushed
hard , a third were used more lightly and the last put out to pasture gently .
A round figure running time could be guessed at , and I have mine . Thanks to Dale
for a " go for it " moment .
