Is there a bart station that goes from fremont/san jose to modesto(if not in modesto somewhere close by there)?

You have two option for taking public transit from Fremont to Modesto. First you could take the ACE train from the Fremont station on weekday afternoons to the Manteca Station for about $10 and then transfer to the MAX shuttle bus for $2 to Modesto. You other option would be to take BART from Fremont to the Dublin Station and take a MAX Express bus to Modesto for $14 one way or $16 round trip from there during weekday mornings or afternoons. Either way it works quite well but if you want to leave in the morning you would need the second option. Good Luck!I'll list the links below
