Wifi/reception - Empire Builder / California Zephyr / Texas Eagle

I have a work from home job and am debating taking a train out west... however, I dont have the PTO needed to do so and have always loved training. just wondering how the train wifi service was out there to see if it's possible from me to work from the train while traveling. everything I do is web based and not requiring a whole lot of bandwidth. any feedback would be appreciated.

Specifically asking for the above mentioned lines.
