Dale Zehner, the chief executive officer of Virginia Railway Express, will chat with riders during an online discussion scheduled for Wednesday at noon.

The chat, which will last for an hour, is the last one for Zehner as VRE’s CEO. He will retire at the end of the month.

You can submit questions early here, and you can participate in the chat at the same place. If you miss the discussion, you will be able to read a transcript in VRE’s archives.
