BART launches diesel services to Antioch

This is actually a branching line of BART networks.
It seems to be appropriate that the line is not electrified to minimize cost on the rail line with less passengers compared with the other BART lines.
But, it's not acceptable that gauge is different from the other BART lines.
If the population along e-BART is increased to be competitive with the other BART lines, there must be through service from e-BART to conventional BART lines.
