Fallbrook? Not as crazy as it might seem...

Would a 90 mph running plan pass in this NIMBY 21st century climate ?
Can a bridge be made to NOT fail in a 100 year flood ?
2.5 miles of a mole hole unless the mole goes boom -
"In 2013, Hitachi Zosen Corporation delivered an earth pressure balance TBM to Seattle, Washington, for the Highway 99 tunnel project.
The bore is 57 ft 3 in.
The machine, named Bertha, has been stalled since December 2013 and remains under repair as of 2015."
Bertha overheated and stalled Dec. 6, 2013, and since then has moved only far enough to reach a repair vault.
Workers discovered far more damage than expected as they took apart the tunnel machine this spring. The manufacturer, Hitachi Zosen, has been identifying additional parts to replace, repair or resurface.
Tunnel-boring machine Bertha, whose front end remains in pieces along the downtown waterfront, is to resume digging Nov. 23, 2015, according to a new timetable from the construction team.
ON TO HISTORY !
"In March 1883, a cloudburst in Railroad Canyon washed out 300 feet of track.
Then came the great floods in February 1884, the wettest season of record.
Even dry San Diego received 25.97 inches and the rainfall at Fallbrook was over 40 inches.
The roadbed of the California Southern was mostly shambles.
There was practically no track left in Temecula Canyon and scores of other sections, including bridges, were washed out.
It was some time before concerted attempts to restore service were made.
By September 18, 1884 trains could run from San Bernardino to Temecula. During the first week of January 1885, the line through Temecula Canyon was re-opened.
Mother Nature dealt another staggering blow in February 1891. "All railroads are washed out." About five miles of track in Cajon Pass were destroyed. Hardest hit, as usual, was Temecula Canyon.
"The expense of rebuilding the Temecula branch is tremendous".
An alternate route was investigated from Temecula to Vista and over to the Escondido branch but nothing was done about it. <-------- (Did you ever look at this route , BOB2 ?)
The portion of the railroad through Temecula Canyon to Fallbrook Station was officially abandoned January 28, 1892"
