Rules vary in the different Bay Area train systems - Caltrain allows patron to bring food & drinks and consume them onboard, while BART doesn't. In the case of VTA, the policy on buses is mostly-restrictive but with exceptions (drinks in VTA containers). I cannot find a similar official link for the light rail however, which is what I want to know.
The trains do have signs about 'make sure to take your trash with you' - which contain the picture of a soft drink can, hence leading to the inference that cans may be permissible.
What is the light rail food policy? Can I hop off at some station, grab a meal from some good restaurant and enjoy it en route; or am I limited to only drinks (or nothing at all)?
