Hi mapmaster,
Interesting map there. I even see the mini-tunnel crossing the laterals in the gasoline storage area.
Did dual tracks ever go as far as the eastern terminus of the rail system above 92nd Garage?
Could the point sets for the second line have been between the west entrance and the single track bridge?

Hi fots2 Yes, this is a interesting plan. It is quite detailed and with measurements in feet and inches. I had to convert every distance to metres before digitising. My opinion is, there was single track from the main line to the west of the railway bridge to near the 92nd Garage Area. The only evidence being the railway bridge is for a single track. Therefore, there must have been a set of points outside Malinta Tunnel both ends. This would mean one of the lines through Malinta was a siding. Below is a photograph of where the Malinta line joined the main (dual track) from North Mine Wharf to Topside. On the right hand side of the photograph is a tram car stopped on the Malinta line.

Hi batteryboy
Photo taken about 1937? Single track over bridge. Track in lower left of the photo goes to Malinta Storage System. Track in lower right is part of the siding in the quarry.
This layout is on the 1936 Corregidor map.
Thanks and regards
mapmaster

Thanks for identifying the layout mapmaster!

love the car too! It's a Sedan, Ford Light, 5 passenger 1941 Model 11-A-73 Staff Car. Here's a comparison reference shot.

Hi Everyone Karl is back from his family's trip to the province. In a circulated email yesterday Karl commented on the image from the MacArthur Museum displaying two tracks through Malinta tunnel. The conversations over the one track and two track photos has been quite extensive and a lot of information and photographs have now surfaced. It is now probably time for a quick summary, accompanied by a better resolution copy of the 1934 Malinta Central System Plan, to be posted by repeating my reply to Karl's email. "Yes, the MacArthur Museum image and the one provided by Tony F. swung the debate back to 2 sets of rail tracks through Malinta tunnel. The 1934 ‘as constructed plan’ of Malinta tunnel shows the recesses in the floor of the tunnel for two sets of track. The early photos of one track appear to have been taken during construction or while construction was on going. The early photos appear to show the single track on wooden railway sleepers (ties). In the early photo of a tram car leaving the tunnel it is possible to see only one power line above the single track. There are two power lines, one above each track, visible on the MacArthur Museum image and the image provided by Tony F.
I’ve attached a portion of the 1934 digital plan of the Malinta Storage System that includes the cross-section of the Central System. It shows the recesses for 2 sets of tracks in the floor. The results from the re-measuring of the Malinta Storage System, we undertook in January 2009, compute and plot exactly with the 1934 plan. This would suggest the 1934 plan was an accurate description of the construction to that date. The attachment is at a better resolution than that originally posted". Thanks EXO for reworking and hosting the better resolution attachment. Regards to everyone mapmaster

Hi Everyone
Steve and Marcia Kwiecinski (residents of Corregidor) have contacted me (yesterday) by circulated email commenting on available information on the question of 'two tracks or one' through Malinta Tunnel.
The comment was: "The 1935 map shows only one line through the tunnel. An engineer on the line says there was only one track. Clearly the picture and the plan show two. Do you see why it is so hard to get to the truth of things?"
My reply was: "The line through Malinta Tunnel may have operated on a one track layout for a period of time. The Malinta West Tunnel Portal is dated at 1932. The original layout for the Quartermaster System was commenced prior to 1934. However, construction of the Hospital System had not commenced by 1934. Therefore there appears to have been work going on adjacent to the main Central System Tunnel. It is therefore probable that a single track was in use for a number of years and beyond the time the 1935 and 1936 maps were produced.
Having said this, there was provision for the permanent two track layout by 1934 – being recesses in the concrete floor for one set of tracks either side of the tunnel’s centreline.
Perhaps the person who knew the single line through the tunnel never knew the tunnel with two sets of tracks. After both tracks were installed, in their respective recesses, there may still have been confusion as tram cars probably went straight through the tunnel both ways on the single track. The siding only being used for loading and unloading.
So, what I don’t know is when the two sets of tracks became operational. At least by 1941 when the film footage, of the 1941 staff car, was taken at the Malinta West Portal. I also don’t know which of the lines was the through line and which was the siding.
So we are slowly finding out what may or may not have been written down, but either way solving what is not available to us.
This illustrates the importance of the Bulletin Board as a form of investigating, researching and supporting ideas. Most of the above has become available through cooperation within CHS and the Bulletin Board as a forum."
We may never know the answer to the questions of "when the second set of tracks became operational" nor "which set of tracks was the through line". But you never know; perhaps one day the answer will appear here.
Regards
mapmaster
