2nd Field Railroad Command and Maj Gen Gyotaro Hattori

Post by Fatboy Coxy » 01 Apr 2024 20:48

Hi all, I trying to find out a little more about the 2nd Field Railroad Command and Maj Gen Gyotaro Hattori.

There was a bit of detail here in this old post viewtopic.php?f=65&t=215805&p=1947147&h ... y#p1947147

I have an OOB for the command here https://military-history.fandom.com/wik ... ember_1941

2nd Railroad Brigade
5th Railroad Regiment
9th Railroad Regiment
4th Special Operating Railroad Unit
5th Special Operation Railroad Unit
102nd Station Command
161st Station Command
1st Material Depôt

Although Brigade might not be the right unit size. Was there any other units attached to this command.

What was the command's original mission when it was landed in December 1941, I know it was later used to build the famous Thai-Burma railway. What units were landed over the beach, and what units came later, probably via Thailand.

Gyotaro Hattori is first shown as commanding the 18th Engineer Regiment, had he been a Engineer officer his whole military career? He died in China, 12 Aug 1944, was that natural causes. See https://generals.dk/general/Hattori/Gy% ... Japan.html

The two main components are the two Railway Regiments, can anyone point me to any information on their capabilities, size and equipment? Where they identical in purpose and organisation.

There was no railroad brigade in IJA. When more than 2 railroad regiments were deployed in the same area, railroad superintendent (鉄道監部) was formed. The commander of railroad superintendent was major general and it had approx. 50 men. Railroad material depot was attached to it.

When the Pacific War began, the railroad units in the Southern Army are as follows.

Southern Army
 14th Army
  6th Railroad Regiment
 2nd Railroad Superintendent
  5th Railroad Regiment
  9th Railroad Regiment
  1st Railroad Material Depot
 4th Special Installed Railroad Unit
 5th Special Installed Railroad Unit

Railroad Regiment consisted of 4 battalions and a material depot. It had 2,470 men.

There is no English source. The equipment of Railroad Regiment is huge and varied according to unit and time. The following is one example.

Hi.

Not really on topic but related:

There is a nice film at the National Film Archive of Japan from 1933 about a railroad regiment on duty in Manchuria showing various pieces of equipment in use while building tracks and bridges, securing railway lines or maintaining a locomotive.

Hi Taki, thank you for digging into it to provide me with something more.

The 9th Railroad Regt was landed at Singora in the 8th December Landings. What sort of equipment might it have carried then, clearly it could have taken freight cars, but it might need equipment to repair some damage to the rail networks

The 9th Railroad Regt did not land at Singora. It moved from Indochina through Thailand to Malaya by rail.

I don't know the equipment of 9th Railroad Regt. But, they captured many freight cars and locomotives in Malaya. They were useful.

There are many more films about various topics, military and non-military, but almost nothing about amphibious operations.

Main site:
https://filmisadocument.jp/

There is one very short film from 1925 about loading men, horses and equipment during an exercise for a landing operation:
https://filmisadocument.jp/films/view/97

and another slightly longer film from a 1922 exercise about the same topic:

Thank you Taki, that makes a lot more sense, much easier to bring what equipment they needed with them. However there was no rail link between Cambodia and Vietnam under French Colonial rule, so my guess is the Regiment must have sailed to Phnom Penh, and disembarked there. Do you have any dates for the arrival of the 9th Railroad Regt, and also of the 5th Railroad Regiment.

Can you also tell me anything about the 4th and 5th special Installed Railroad Units, their composition, use and dates please

Hi Tom, thank you, again really lovely, its nice to see how they did things back then, and it can greatly help if your writing a story with amphibious operations in the background.

Hi Taki, fascinating films, made for the Japanese cinema's, very similar to the British ones. Wish I knew what the commentator was saying, wonder if he finished the script with a little funny line, just like they might on Pathe News, love it. Have a look at the soldier climbing down the rope ladder at 0.34 on the Singora film, the weight he is carrying, with the rope ladder swaying about, if he falls in the sea he'll just sink straight down!

Can anyone identify the landing craft in the Bismarck Landings, I think they might be Daihatsu's

Leyte Gulf is a great video, but again I'm poor at identifying the tank at 1.15, and the truck at 1.24. There is a great shot at 1.42, two Daihatsu unloading, with a third behind offering a side view, showing the high prow. And at 1.54 it's the good old fashion way of unloading by man power, not dissimilar to how the US Marines were doing it elsewhere.

> However there was no rail link between Cambodia and Vietnam under French Colonial rule, so my guess is the Regiment must have sailed to Phnom Penh, and disembarked there.

Railroad regiments laid rails. The railway between Saigon and Bangkok completed on Dec. 10th.

> Do you have any dates for the arrival of the 9th Railroad Regiment, and also of the 5th Railroad Regiment.

5th Railroad Regiment arrived at Saigon on Aug. 24th, 1941. 9th Railroad Regiment arrived at Haiphong in Oct. 1941.

I correct my previous post. A part of 9th Railroad Regiment landed at Singora and captured Malaya railway.

> Can you also tell me anything about the 4th and 5th special Installed Railroad Units, their composition, use and dates please

They were formed on Sep. 13th, 1941. The personnel were mostly civilians mainly came from Japanese National Railways. Soldiers were only 29 men. The commanders are major general. They were equivalent to railroad regiment. The composition is as follows.

4th Special Installed Railroad Unit
 HQ
 10th Special Installed Railroad Transport Unit
 7th Special Installed Railroad Building Unit
 4th Special Installed Railroad Bridge Unit
 4th Special Installed Railroad Work Unit

5th Special Installed Railroad Unit
 HQ
 11th Special Installed Railroad Transport Unit
 8th Special Installed Railroad Building Unit
 5th Special Installed Railroad Bridge Unit
 5th Special Installed Railroad Work Unit
