In June 2013, at the cross-railway of Jinyu Avenue in Chongqing, the leftmost line was the line connecting the Chongqing North Railway Station, and the right was the newly paved Yuli Line and the Yuhuai Downward Line.
At that time, the Chongqing North Railway Station was still under construction.
Back next to the Yuli Line, a newly long painted Dongfeng 4B diesel locomotive was transferred to the Engineering Bureau for use.
Along the Yuli line, the two on the left are the Yuli main line, the right is the Yuhuai downward line, and the Yuhuai uplink line is in the tunnel next to it.
After a parallel period, the Yuhuai downward line is separated from the Yuli positive line.
Next to the Yuhuai Line, the Inch Beach Special Bridge.
On the other side is a laying machine, which is the outer winding line of the truck in the direction of Yuhuai Yuli, that is, the contact line of the XinglongChang to Hudoubao line via Tangjiatuo.
The Xinghu Line Huofengshan Tunnel, 9.4 km long, crosses the Yubei people and below the street.
There are two tunnels on the Xinghu Line, the Moyubao Left Line Tunnel and the Right Line Tunnel.
In front of it is the Yuli Line Bird's Nest Tunnel.
Next to it is the Yuwan Passenger Line Bird's Nest Tunnel, as well as the piers of the Airport Expressway.
Walking out of the bird's nest tunnel, the other end is different in style, next to the Yuwan bird's nest tunnel.
Ahead is a curved bridge.
The Commons Dam Tunnel, this one shorter than the Bird's Nest Tunnel, is able to see the other end.
Step out of the Commons Dam Tunnel.
The mountain in front of you is Yufeng Mountain.
Two Dongfeng 4B diesel locomotives pulled flatbeds loaded with rails through.
Look at the unpaved bridges and tunnels in the distance, which are the Xinghu Line from Tangjiatuo to Hudoubao Line.
Notice the unpaved line in the lower left corner, which is the xinghu contact line.
The tunnel on the right is the Xinghu Liaison Line going down.
In front of it is the Hudoupu Line and the Yufeng Mountain Tunnel.
Movable turnouts to increase the speed of passage.
A Dongfeng 4B diesel locomotive pulls the carriage and stops here.
The 3.2-kilometer-long Yufengshan Tunnel is next to the tunnel of the Yuwan Passenger Dedicated Line.
At the end of the visit, the total distance from Jinyu Avenue to the mouth of the Yufeng Mountain Tunnel is 11 kilometers.
