BNSF is building a 3rd Main Track thru Cajon Pass. It will be built along the #
1 (north) track (2,2 % grade). The only 2 tunnels in Cajon will be daylighted.
I am very proud to show these pictures taken by Don E. Toles and Gary G. Gray.

Photos 100 - 201 on this page starting September 08, 2007 and ending October 25, 2007
|9/11/07 UP SB at Sullivans Curve - 100||9/11/07 Natural Gas pipe relocation at SC - 101||9/10/07 Cajon Station North staging area - 102|
While checking out Sullivan's curve on Sept. 11 for construction activity, I photographed a crane supporting an oddly configured large diameter pipe. I also noticed that the ground had been excavated on the right-of-way road next to nearby #1 track, and the excavation had been covered with heavy steel plates in order for the road to remain in service. Although I knew that a high pressure natural gas pipeline passed under the track near Sullivan's curve, it didn't occur to me that the large pipe and the steel plates had anything to do with the gas line.
Friday AM the 14th found me on Hill 582 with a load of water for the trees. A high-decibel, steady roar that sounded like a jet engine or a helicopter revving up for takeoff was coming from somewhere east of the Hill. After dumping my load of water, I drove east on the Forest Service road next to the SP tracks to see where the loud noise was originating. About a half mile east of Hill 582 and south of the #2 track, there's a fenced-in facility built over the high pressure gas line. I could tell that something was going on there, as several trucks and a porta-potty were parked nearby. I concluded that the noise and the strong odor of natural gas was coming from that installation.
On Sept. 14 someone posted the following notice on TrainOrders.com:
"The So.Cal Gas Company is going to vent off the 36" main that runs down the Cajon pass this weekend, starting at 0600 on Sept. 14th and concluding at 0700 Sept. 17th."
The post goes on to explain that the gas line was being vented and purged with nitrogen gas to remove the natural gas in order to shut down the pipeline so it could be modified where it passes near the new 3 MT. That odd piece of pipe (101) that I photographed has most likely been installed now at the west end of Sullivan's curve. Mystery solved! (DET)

|Pictures 110 and 111: Last week Ames Construction started grading and "filling" the inside of Sullivans Curve--that's a really deep ditch and it'll take many loads of "fill" to get enough surface for the new 3MT.|
|9/30/07 New ROW WB across Hill 582 - 112||9/30/07 New ROW EB across Hill 582- 113||10/05/07 Summit looking EB - 114|
112 and 113: Here
are the new views from Hill 582 showing the sub-ballast "super
highway for Railfans".
Picture 114: Note that EB, the new signal bridge appears to be in operation for the existing tracks. Also note that there is a solar "green stuff" generator. Thirdly, on the left, the new 3MT has rail and concrete ties in place extending from the existing Martinez siding --- but not tied down. Someone said today that the "RAIL LAYING" machine will be here shortly. It also appears to me that the bridges, fills, and ROW are in place and ready for rails from Summit to the EP of T-1. (GGG)
|10/05/07 Tunnel 1 EP - 115||10/05/07 Above Tunnel 1 EP - 116||10/05/07 T-1 Looking east grading on top - 117|
Last Friday, I (GGG) got back to "the Hill" with DET. It appears that removal of the dirt above each tunnel is governed by the downward progress of the "shotcrete" retaining wall". Dirt removal has shifted to T-1 with an interesting seven picture story -- I think (Photos 115 - 121).
Photos 115 and 116 show T-I EP with the backhoe equipment and trucks. Note the hammer drill working on the "sleepers/deadmen" after the shotcrete is sprayed upon rebar. Also, note that the crushed rock sub-roadbed now extends to T-1 from Summit (115).
Photos 117, 118, 119 show T-1 from the WP area. Ames has built a two lane "haul road" to bring the excess dirt down to track level between the tunnels.
Photo 120 looks WB at T-2 EP. The loaded truck(s) climb over T-2 WB.
Photo 121 looks EB at T-2 WP where the loaded trucks descend to track level, proceed to the BNSF # 2 track, follow # 2 under Interstate 15 to near Davis Ranch, cross the # 2 and dump in the borrow pit.

Here are three pictures (122 - 124) of the BNSF 7511 and the 3MT progress at Sullivan's Curve. Ames is building a retaining wall for the new track.
The Ethanol train, with Four pulling and Three DPU's pushing/braking is WB at Sullivan's. The detector said that the train had 434 axles, which according to my calculations (42 powered axles and 8 idler car axles), leaves 96 loads (GGG).

To bridge Cajon Creek at East Cajon Station, Ames Construction is required to drive pilings into the soft earth and drill into the rock. Here's the equipment necessary to complete the job.

|4 photos (135 - 138) from the Blue Cut/Swarthout Canyon area. The main San Andreas fault crosses at Blue Cut and the area is made of some kind of crumbling rock, actually Pelona schist. The same rock was partly to blame for the St. Francis dam disaster. (This helpful information was given by Charles R. Sainte Claire, P.E. Caltrans District 08). Therefore, Ames Construction appears of be able to drill the rock rather than blasting ??? (GGG)|

Yesterday (10/12/07), after our Friday "RailFan Bunch for Lunch" at da dump, several decided to visit/revisit Cajon. And so, in the late afternoon with a minor storm approaching, and after a minor confrontation with Cajon Security, I got the attached four (139 - 142) from between the tunnels.
Tunnel 2 appears to have just 10-15 feet of dirt remaining above the concrete tunnel lining, however, there's still plenty of work to be done. (GGG)

BNSF has started laying track from Summit down to T-1 EP. The track is being placed upon the sub grade ballast. Obviously, the ballasting and surfacing gangs will follow. Here is DET's narrative of how this whole system works ---- with attached and numbered photos from the West Summit Island area. (GGG)
1: (photo 143) This Herzog Tie Laying Machine (TLM) is just that -- a tie laying machine. 2: (photo 144) It lowers each concrete tie to the roadbed, precisely spaced and aligned. The machine is slowly pulled forward by a Caterpillar tractor that is equipped with a device on each side that holds the rail above the roadbed and spreads the rails wide enough for the concrete tie to drop into place unobstructed. 3: (photo 145) A narrow dolly between the rails with dual caterpillar treads supports the front end of the TLM. A diesel engine powers the hydraulic system that runs the mechanism that moves the ties forward and drops them on to the roadbed. 4: (photo 146) Behind the TLM is a series of specially built flatcars that carry the concrete ties. Each car holds two stacks of ties with five layers of ties in each stack. 5: (photo 147) A diesel powered shuttle buggy straddles the stacks of ties, running on rails mounted along the sides of the flat cars. The shuttle buggy moves back and forth above the stacks, picking up a full layer of ties, moving forward to the TLM, where it lowers the entire layer to a platform where the ties move onto the conveyor that takes them down slope to be dropped into place one at a time.

Also, this sequence shows the current End of Track for the new 3MT and the amount of dirt still to be removed.

174 - 179: After the TLM lays the new ties and rail, a different machine
called a "CLIPPER" goes to work permanently attaching the rail
to the ties. We could not figure out exactly how this
"Clipper" machine works. So, we asked our resident MOW expert,
Paul Westover (UPRR). Our
questions are in red.
The large letters refer to the attached picture # 179.
- Thanks Paul - (GGG/DET).
Q 1) It looks to me that the clips ahead of the Clipper Machine are down -- see the X. After the mechanism at Z does it's thing, the clips at Y (both 3MT and the #1 track) appear to be "UP" and locked.
A 1) Yes the clips are down and come with the ties pre installed but not locked into the tower. The style that is most common is the Pandrol brand "Safelok" these can be seen on the former SP line, the south trk has I believe the Pandrol "e" clip style or the modified style. The type being installed on M 3 is similar to the safelok but more advanced with the integrated biscuit onto the clip. The clipper car would simply push the clips in and lock them into place. The clips in photo "Y" are an advanced or refined style of "E CLIP" just a different style for a different type of tie, The tie having the tower built in to use a certain style of clip. In the photo the Herzog worker is probably setting or replacing damaged clip/biscuit assemblies.
Q 2) The TLM and tie cars are traveling over newly laid track which is NOT "clipped" permanently to the concrete ties. Why, under all the weight, doesn't the rail roll over ???
A 2) The weight alone keeps the rail from rolling over as long as there isn't any violent bunching or stretching causing it to tip over. The base of the rail is 6" wide which isn't a lot but the forces of the cars moving at slow speed will be transmitted downward versus a train traveling at let's say 25 mph would generate a lot more lateral force (pushing the rails outward) as long as the locos handle the cars with care there should not be any problem, I have not heard --- not saying it hasn't happened, of a train rolling over unclipped track while swapping loads for mts --- but I can see where it would be plausible.
