Again, this will help increase productivity and efficiency for riders. Although VTA does show times on the paper bulletin, it would be easier for riders to look up and see how many minutes the next train will arrive.
This should also include: service advisories, active updates on *recent* delays, etc. By doing this, VTA can easily upgrade its current light rail infrastructure to that of a subway.
Also, these signs are EXPENSIVE. If we have them now, why not make better use of them than to display "No smoking" and fare-evasion consequences? This would not cost a lot to VTA to implement.
And even if the express trains do get implemented, VTA can easily display information regarding these trains, when they will arrive next, and other important info. These signs have a LOT of potential.
