Hello, so, when passing over a turnout on my layout, the trailing truck on my SY 2-8-2 derails. It is the only thing that does. I'm not suprised as it has always been more sensitive to issues given that it has little pressure downwards. That said, Something is still wrong that it comes off at taht same point every time. I've looked very close and found that at a point almost to the end of the points, the truck lifts and the wheels ride the rail before dropping off as seen below:

I do not see any issue with the turnout but I thought I'd ask if anybody more experienced saw anything. Here is the turnout empty:

have you chequed the wheel guage of the trailing wheels against an nmra guage? they may be a little wide.
also, I notice the points are a bit blunt. you may want to carefully file the inside edge of the points where the wheel flanges run so that the end of the points come to a sharp point instead of a blunt edge.

jward's advice on checking wheel gauge is important as is the filing of the gauge side of the points. That closed point looks as though it could be a little more snug against the stock rail.

"Snap" switches are notorious for their questionable performance.
Jward's advice of filing the points is the best solution. The points should be almost razor-sharp to prevent "jumping" of the pilot/trailing wheels.
If you don't have a set of jeweler's files, get one. You'll be glad you did...

So I should file the inside of the point, thinning the rail?. I don't have jewelers files but I do have a larger file, would that work? I don't posses a gauge but It is not like I could replace the truck anyway and it has no issue over all the other turnouts on my layout.
Brick, get an NMRA gauge and a set of jewelers files. I have mentioned here before, the gauge can also be used to check turnouts/switches, whatever people are calling them these days.
While jewelers files are the way to go, short term you can use a fine grit emery board will get the job done. You'll find them around the ladies cosmetics section of most grocers.

Ahem, I would get (invest) in a set of jewelers files, they can be found for inexpensive cost and have a variety of shapes and sizes that will come in handy, maybe not today, maybe not by tomorrow, but definitely sometime in the future of you train modeling future (this is if you intend to grow in it).
BTW, if you do go to the ladies cosmetics section of a store, pick up some makeup q-tips. They have good uses and are better than the standard q-tips.

Not sure what you mean by "inside of the point". You should file the face that does
NOT come into contact with the outer rails.

The points on the other side of the track from where the picture was taken.

The points are in the foreground of the picture.

Since I need to go to home depot tomorrow anyway to pick something up, I'll ask about jewelers files. I hope that can fix it as, as I have stated many times, the SY it my favorite Locomotive and I hate that this little thing cases problems but as you can probably imagine, one little derailment can cause bigger problems.
I am not sure they will have them there bro, or if they do, how much they will be. I got my set from AMAZON under "needle files" and looked up their cost last night. Total cost was $5.45.
Irbricksceo : go to the Micro-Mark website if you cannot find needle files at Home Depot . Micro-Mark is a supplier of tools & equipment for model builders & also carries model railroading equipment. Good Luck . John2
He can, but I am betting that they will be more expensive than AMAZON, especially when you throw in shipping. My price included shipping, ie: "Total cost".
If you have a Michaels or AC Moore craft shop in your area, you should be able to find small files there. Either in the tools or jewelry making section.

I purchased my files from Harbor Freight (online) several years back...

Good suggestions.
For shopping at Michael' s, don't forget to bring a coupon for 40% (sometimes there will even be ones for 50%). If you don't get coupons in a flyer, you can go to their website and download a 40% off one. Also, they will take competitors coupons, such as from Jo-Ann's Fabrics. The coupons are used for REGULAR priced items and make for a good deal.

The "inside" of the points is always the gauge side. Ditto for the "inside" of a rail. The part of the rail where the wheel flanges go. :)

well, HD had em but I found a better price on a similar set on Amazon so I'll just wait for them to get here in a few days. in the mean time, I need to resolve the issue with my 2-10-0's lead truck hopping (shouldn't be too hard, I think it just needs some adjustment) and figure out how to extract the screw from the back of the 2-8-0 that got stripped. Plenty to do! I'll update the if the files work I suppose.
You're welcome.
