Android: If you use public transit to get to work, Google will sometimes let you know if your train is delayed. However, it might not tell you until you get to the station. This Tasker action can help by letting you make on-demand requests to find out.
The Tasker profile was put together by XDA, which you can download at the source link below. When you set it up, you can use a voice command to ask whether the trains you use frequently are on time or running behind. It's a handy tool since Google's transit cards don't always show up when you want them to. The guide on XDA will walk you through the steps to set it up.
