Evening
Thanks for the continued idea methods here. Its appears hot water or hair dryer suggestions are pretty even recommendations.
I melted some bridge members with a hair dryer Rich, so I know what you're saying. They were deformed to the point that I could not straighten them again. I won't have the luxury of grabbing another stick of styrene if that happens with the railing.
I see you suggested hot water as Overmod did as well. I think he suggested a temperature of 163 but not over 165°F. And I'm liking Douglas's idea of covering up the top of the railing with weight leaving only the warp exposed to the heat. I see FScotsman leans towards the hair dryer idea as well.
Selectors idea of using the tip of a soldering iron does make perfect sense pinpointing the heat source only where it is needed. Perhaps holding it an 1/8" away or so.
The hot water ideas have me a little baffled on how to control the directed concentration. I'm thinking of a glass eye dropper with the 163 degree water taken out of the pot on the stove dripped on to the railing on the glass table with the V notched dowel ready for the jiggle pressure.
I think I have enough scrap railings around here for 8 experiments. I found this guinea pig and have another one around here somewhere.
Wouldn't you know it that the railings of the Delaware and Hudson shell are perfectly straight. I have two good U36B's but won't be having any (just in case) railings anymore
Thanks again for all the help gentleman

I also picked up a few good ideas from this thread.
Thanks everyone.

Just to be clear. The idea is that once you weigh down the railing flat, its in the correct shape. So you do not need to heat the plastic to the point that it becomes pliable...which would be near the metling point....but just enough heat to begin to release the tension that's causing the warp.
You could probably do that with a soldering iron held far enough away too. One staunchion at a time. Maybe an eyedropper of water too, but it would probably take multiple drops and be harder to control the overall heat.
You can actually unwarp delrin handrails by overbending them opposite the warp...stretching the plastic in the opposite direction so to speak. And they will settle back to straight. That's the only way I do it now, since I have newer vintage locos and its pretty easy to manipulate the newer plastics than handrails of some 15 to 20 years ago, IMO. Some handrails are too brittle to take much overbending.

Warped railing update.
Before
After
I put masking tape over the teeth on a small needle nose tip. Put my model on a towel on the stove top. Carefully held the railing with the needle nose. Then stuck a Q Tip in water right after it boiled and held it on the source of the bend. While hyper-extending the bend from the source and held it for a minute.
Got it. A bit of yellow paint touch-up to do that didn't happen on the experimental railing but I think I can live with that.
Thanks for all the ideas and advice here gentleman as it was very helpful and appreciated
It took a few dips and application of the Q-tip before the new memory held its own but it worked Mike.
Very nice, TF, and I am happy to read, after so much discussion, that you found something that worked. A good day, and you get to enjoy looking at your diesel as it should be.
Thanks Selector. Also for your help as well
Well, So much for fixing the railing! It's a Dark Day at Fiddler's place.
SHE'S A GONER! I was working on a bridge and have no idea now why I had my new model sitting too close to the edge.
I guess even padded carpet can be a rather destructive landing when the lid flips off.
This is my all-time most destructive locomotive fatality ever. Even with all the pieces accounted for there ain't no fixing this
Unhappy Track Fiddler in the house!
Sell it on eBay as NOS.

Look at the bright side. Now you have a source of spare railings.
I was thinking the same thing. Looks fixable from the pics. If there are truck parts that are cracked or broken, then its pretty tough.
The sill can be fixed with solvent. It may be possible to use plastic strips to strengthn the joints, unseen on the bottom.
If the sill is not used to hold the entore shell onto the frame, then there should not be a bunch of force on the newly bended joints.
TF, take a deep breath. Do you remember when Mark Pruitt did the same thing about 14 months ago...but to his large roundhouse? We all advised him to get his seething under control, go for a walk, a long one, have a donut, and then come back with a determination to put it back together. It took him a day or two, but then it became history, and you can do the same.
Give us close-up shots, several angles. You'll get some good assessments and advice. In two weeks, this will all be history. Either that or look for a shell on eBay.
Hey, there must be some pretty good sales now that we're past the Silly Season!
PS- I imagine you'll want to repaint your walls and backdrop first, though. They must look pretty bad after all the bad language.
Doughlessf there are truck parts that are cracked or broken, then its pretty tough.
Both Loctite and LePage have bonding agents that will work on Delrin and other engineering-type plastics. I couldn't find the Loctite version locally, but did find the Lepage one.
It's basically a ca, and a separate "activator", which comes in an applicator that ressembles a small marker pen.
The procedure is to rub the applicator onto both surfaces to be joined (it seems to be colourless), then wait about 60 seconds for it to dry. You then apply the ca to one of the surfaces to be joined, then bring them together.
The "activator" seems to have considerably more volume than the supplied ca, as I quickly ran out of the latter, but found that any ca can be used with the activator.I'm uncertain as to the lifespan of the activator, as I've needed it on only a couple of occasions.

Hi TF,
That's terrible!!
I'm going to repeat what a couple of others have suggested. Give it a few days. Glue is good stuff.
Cheer up!!

Good morning
Thanks for the vote of confidence in your replies after my DMIR Catastrophe yesterday. I wasn't even contemplating repairing this thing until you guys chimed in.
The first thing I did after cooling off a while was check to see if anything was broken on the truck as Douglas pointed out would complicate repairs.
The truck was fine so I held the contact strips down and twisted it back in from a 45° starting position and repositioned the strips. It does run just as smoothly as before.
At that point, I was so flustered with disappointment I did what felt like a locomotive funeral putting all the broken parts in tupperware. I even put one of Judy's best washcloths on the bottom of the casket so the broken parts we're comfortable and wouldn't rattle around in there.
I wrote down your information on the specialty adhesive and activator for Delrin plastic in case I need them for the repair or something else down the road. Some valuable information and I thank you for that Wayne.
As Douglas and Mike pointed out, styrene solvent may work for the repair on the sill. With experience with that on bridges gives me a lot of hope. Also Selectors comment on Mark Pruitt's success of fixing the Round House gave me some encouragement as well. And your comment was correct Selector. The words that came out of my mouth when this happened were the ones from my more filthy vocabulary
Thanks for your vote of confidence as well Dave. I'll be trying the solvent and glue recommendation stated here. Also the glue section at Menards is almost overwhelming. If a guy had a clue and only knew what all that glue can do
If all else fails, perhaps I can sell it on eBay NOS as Rich stated. Or add it to my MR junkyard in case I need railings or other parts like Maxman said.
For now, I'm still too disappointed about this avoidable accident. I think I'll let things simmer another day or two before dealing with it.
Thank you for your support
I had an HO Kato dash 9 crash on the concrete floor, from about 50" high. I gathered all the peices I could find, set it all in a box, kept gathering pieces as they appeared.
I took it all apart, the rear truck suffered the most damage, I was able to carefully piece it all back together, and back in service.
I did order a new truck assembly from Kato, and when it arrived, I replaced the peiced together truck with the new one. I think the new truck, at that time, was about $25.
N scale would be a challange for me, but I'm sure you can put this back together.

About 45 minutes this afternoon and the Tamiya solvent worked like a Champion.
She's back in one piece and the only flaw worth posting a picture of is the last joint I put together before I fastened the deck sill and railing back onto the locomotive.
Short of perfect but a little black paint and some yellow on the railings. I don't think anybody will ever know the difference.
Thanks for all your help gentleman
That looks great. Congrats.
If you're at all like me, it still leaves you feeling a little sick, TF, but that will go away in time. My three disasters, all with one misstep and grabbing at the rickety shelf, seem like a long-ago shrug now. They all run just fine, and look good.
I'm happy for you.
