Attack on German train Holland september 1st 1944

[Richard1976]

On the morning of September 1st 1944 (around 9.00hrs a.m. CET) a few trains were attacked in the vicintiy of Roermond, The Netherlands. One of those trains is of special interest to me. It's a German train fully loaded with ammunition heading from Mönchen Gladbach (Germany) to Roermond which was attacked by (probable) P-38 fighters. As one eyewitness told me about a half year ago that 2-tailed planes were involved in the attack. An characteristic shape which he never forgot. Also a local historian told me P-38's, but unfortunally he doesn't have more information. The train stopped just a few miles to the east of Roermond and was completly destroyed. I've checked the police file and Air Raids Protection (I hope this is the correct translation) file for september 1st '44 and both don't mention that 1 or more planes were shot down or crash landed in the area during the attack. So likely no planes were lossed. It probably was/is a little bit easier to find some information when a plane was lost during this attack. Somewhere there must be some information about this, but I'm a newbie in the air war and I don't know where to look. Do you know where I could find more information about this attack/raid and the fighters (squadron) involved?

Thank you. All help is appreciated.
