Closed course. Non-union driver. Do not attempt in Bernal Heights.

Those fuel-huffing fathers from Bernal Dads Racing are pleased to announce that as part of their effort to move Muni Forward, Bus 670 will offer  24-hour super-express transit service on a trial basis this weekend,  from 11 am on Saturday, March 25 until 11 am Sunday, March 26.

As every SFMTA enthusiast knows, the Muni Forward program is about making it easier and safer to move around San Francisco. Based on feedback from San Francisco transit riders, the Bernal Dads have taken it upon themselves to explore the possibility of providing  faster, more convenient, and more reliable super-express Muni service anytime, day or night.

To accomplish this, Bus 670, a 1992 Volvo 240 wagon fitted for public transit duty and enhanced with a high(er)-performance BMW engine, has been further upgraded with an advanced photon-emission system that enables the vehicle to turn night into day at the flip of a switch. This video was taken during a recent test of the system:

With those modifications complete, Bus 670 will head to Buttonwillow Raceway Park this weekend to study the feasibility of uninterrupted super-express Muni  service by participating in the Lucky Dog Racing League’s “Doggone 24” competition, a continuous, 24-hour endurance race that will provide a realistic simulation of extended-duration rapid transit operation, driver fatigue-management, and intense maneuvering in wheel-to-wheel San Francisco traffic.

“This Muni Forward infrastructure improvement was funded entirely with loose change the Bernal Dads found beneath the cushions of our sofas, with no support whatsoever from Prop A, the bond measure passed by San Francisco voters in 2014. We have listened to Muni riders and look forward to reducing travel times and increasing high-speed service in a rapidly growing city,” said Neighbor Brandon Powell, Bernal Dads Racing’s Director of Advanced Projects.

To monitor this important public transit experiment and get regular NextMuni updates on lap times and anticipated service intervals, aspiring passengers are encouraged to visit Bernal Dads Racing on Facebook throughout the weekend. And as always, thank you for riding Muni.
