I have more of those than I care to count.
The biggest problem with the "No Plan™" plan.
I have several kits and have no place to put them.

I have several Walthers kits that I bought when at the "Plan 1" stage of my layout, now I'm on "Plan3 (revised)" stage and they no longer fit.
No matter, I've overcome my Buyers Remorse and decided on a significant amount of Kit Bashing when I'm at the correct stage of development.:thumbsup::thumbsup:

 

I am not sure if I would call it remorse, But I have bought a lot of kits to make an airport and have never got a round to making any of it.

 

Haha, I recently got into model trains (December 2017). My initial interest was ‘60-‘70s CP passenger stuff.
Bought a Rapido FP9A and an Intermountain FP7A along with six Athearn Heavyweight cars.

My interest changed to freight and SD40-2s (1980s) ...and therefore selling/sold my passenger stuff and eight Intermountain boxcars.

A bit annoyed at myself for the extra cost of changing gear, but am glad I figured out what I like.

 

To Dream of Empire!!

I have found over the last two years that maybe I should reign in my tendencies to Dream Big!! Engine House Services in GB has so many sales and Walthers Kits are HUGE!! My future Paper Mill...is on hold...again...TBA!! LOL:laugh::laugh::laugh::thumbsup:

 

My heart says "Buy it!"
My wallet says "Ain't no way, Jack!"

 

[ I'd been looking for an SD40, and there was an Athearn with sound on the shelf for $89. I jumped at it.

... It was actually an SD40-R, which is several years outside my era.

Was that a Southern Pacific SD40R? Which number? I have two of them and I model the late 1970's thru early 1980's. IIRC, the SD40R's were rebuilt in 1980 and 1981 according to Utahrail.net

We all have buyers remorse. My cure to that is to sell off the things I decide don't fit for whatever reason, which I've been doing over the past 10-12 years now, whittling down stuff I don't need, either due to switching era's, some kits I'll never build and other reasons.

That would put your era into 1980/1981....if you want to be prototypically accurate....

But It's your railway, so you can run whatever you want....

I try to model the 1960's, but I have early 1930's to late 1970's cars, and I'm happy....

 

And from even earlier than '77 (chronologically)....but not later than '83 (anachronism)......

 

My "drawer-full"
To be clear, I do have a 'drawer full' of stuff that I have no intention of using, but with no buyer's remorse attached.
For instance, cars I've picked up at sales and 'give aways' that were too good to pass up, but are way out of my era.
There's no way I'm going to forgo a $35 ExactRail car sitting on a table for 8 or 10 bucks, regardless of it's vintage.
For the right price, I'm liable to grab anything from kits to RTR... Stewart & Accurail, to Athearn, Bowser, ExactRail & Tangent.
At virtually every meeting I'll get a small-profit return from someone who wants them (I rubber-band the original receipt to the box).

I currently have 30 or 40 nice cars in a two-door steel locker-cabinet... all in the '70's-to-'modern' eras. Before I leave for a meeting, I'll grab a few, and almost never return with them.

It's interesting that modern covered hoppers seem to be the latest rage around here.

[Note]:
I won't do this with locomotives.
Learned my lesson long ago.

 

Not been in the hobby long, but I've been planning ahead for buyers remorse by patiently hunting down super-duper-deals on what I want and only impulse buying stuff that is stupid-cheap so that I can faily easily sell anything I decide I don't want for what I paid for it or more.

 

I've found a couple ExactRail cars in the $10-15 range but I don't find those prices very often.

There is a cure for buyers remorse - HOSwap

 

Years ago when I switched from N scale to HO scale I started doing a lot of custom painting and detailing of both steam and diesel locomotives and still have quite a few detail parts in parts drawers that I probably won't use.

The saving grace is that at the time I had a Walthers dealership and was getting everything at wholesale.

So far as my layout goes, Before I even started laying any track, I had decided on what era that I wanted to model and stuck with it. If it didn't fit, I didn't get it. I even got my magnifiers on and read the freight car date to make sure that it was not too new. No vehicles on the layout are newer than 1957 whice is the year that I choose.

I did run across a few building kits that I never used. Having no hobby shops at all where I live, I would stockpile items that I would pick up at various hobby shops when we took a road trip and occasionally forgot where the heck I put them. I have been able to get these unused kits to people on the railroad forums I am on so they did not g to waste.

Although I do like many of the modern diesels and rolling stock, I will not spend any $$$ on them.

I am a DC operator at home, but at my club, they of course do operate with DCC and I have picked up a few DCC locomotives to run at the club, but they are still in the era I model. If visitors come over and want to see the trains run, I may put one on the rails so the sound will operate to some degree. I can live without sound when I operate at home. Whem I'm working on the layout, I will usually try to let trains run while I'm working and will rotate through my roster to make sure that no locomotives just sit areund, which is really not good and will let each run for a while. I find that after a short period og time that the sound locomotives just drive me nuts.

If I can't use it, I do not buy it, no matter how tempting.

 

Most of us who have been in the hobby a while have our "unbuilt kit repository" - items we have picked up when they were available and/or would have a purpose on the layout at some point. I have about dozen C&BT On3 EBT hopper kits to assemble and a bunch of structure kits. I expected by now to be much further along with the layout and having spaces for said kits, but life had other plans. I still have some HO that I kept, and have added some to operate on the HO club I joined in PA a few years ago. That layout has been DC but they are starting to convert over to DCC so I've acquired some dual mode locos for that purpose.

 

So far in my HO modeling career I've only bought one structure I wish I hadn't.

This was a very recent purchase of my track walk-over. I thought it was wider than it is and would span three tracks. It only spans a dual line, and it won't even fit between any two of my three station tracks.

I might cut it up and widen it for all three tracks.

 

Even though I know I won't use them all, I won't feel remorse for any of the stuctures, or structure parts I purchase(d). Part of that is that I'm buying at the low prices I mentioned earlier.

Mainly though, when it comes time to put structures on my layout I want a stock big enough to be able to kitbash and customize at will without having to put a project on hold to source a particular part or bit.

It's roughly the same approach I take to building sci-fi wargaming structures I keep a big stock of parts, materials and broken toys around that I can chop-up, reassemble and greeble however I like.
