Has there ever been a Lincoln Passenger Train?

Husker GameDay Train?

I recently took an Amtrak ride on the California Zephyr from central NE to Denver. Worked really well and it was nice not having to drive. Especially considering Scottsbluff to Lincoln trips being 8+ hours of driving, jumping on a train ride overnight to get home would make the trip much easier. What stops Amtrak or UP from doing a husker train the day before and day after games to service the bulk of Nebraska?
