Just added these

[Super]

Are there real flat beds that carry 5 containers?

Yes, all Kato models are based on real rolling stock.  They also have some flatbeds that have double decker large containers as well

They look nice. also, the containers looks like they are attached to each other? I think that way because I actually own one, but at the very last container, it is replaced with a caboose.

I also have this


But it is more to the rust color brown and it has the top covering it, shaped so it looks like it is covering boxes/crates in it.

ps: my container caboose thing is missing the wheel, since my brother stepped on it, I just wanna ask which one do i need to replace the wheel? (it's like the whole bogey tho) 
example replacement part:


Although, these look a little longer on the coupler, and they use a screw to put it on and mine uses a clip to put it on. are these the same? pls help me?

I didn't actually know you'd got any Kato 'N' Scale   There are various bogies available so you probably need to get a specific type, I'll see if I can find out which it takes, although I suspect it will be the same as the container flat cars, I'll take a picture of mine and you can confirm if its the same type and if so then I'll go see if i can figure out which is the appropriate spare part.

Ok, I've had a look around and the type you need for that wagon is this; Kato Part Number 8002D

Here's some pictures of the bogies on my wagon;







Incidentally you were right, the containers are a single piece moulding, just goes to show I always thought they were 5 individual pieces not one piece

These ones may work as well as they seem to be very similar, except for the outer bogie detail being different; Small Trailer Bogies

Thanks mr nigels! i am incidentally right again, the bogeys on your container cars are put in with a clip. i do not see a bolt on there. I do know and have a container car that you can acutally pull the container of off. From the starter set ef210 and it has container cars. maybe you can gett the container cars by themselves, and buy the containers themselves, because i saw in my local hobby store, although 2 yaers ago, a pack of kato containers.


another version:


The red ones is the ones that i got with the set.
(THe container cars use the bolts to put the bogeys toghether and they are grey, instead of black).

I think you are right on both counts as I've been looking through some dealers parts/wagon listings and found several different wagons listed that look the same, but carry different model numbers and pricing.  When I say different pricing I mean the ones with the single moulded set of 5 containers are lower priced and the other models - not sure if they have individual containers are nearly double the cost.  Unfortunately my Japanese is rudimentary at best so it could be the ones with the single moulded 5 containers are a budget model and the other if it has individual containers is a deluxe or standard model.  It wouldn't be the first time I've seen a manufacturer do something like that...

Here's today's additions some nice large steel box cars (3 of), a one off 'Roco' funky looking car and an EF66, this again has working lights, but like the other EF only white headlights on the direction of travel, no red lights on the rear...
