I kind of remember these?
I'm assuming this one is the old Walthers hopper?
But this one looks like all new tooling?
It is, nevermind.
The top hopper is the BLMA hopper...
No it's not.
Look at the details: Ladders, brake wheels, roof hatches and foot stirrups.
It's always nice to see new releases. Shows a healthy market. Shame they are to recent for steam power.
The PS 4427 hopper is an ex-Walthers car (one of several former Walthers cars Atlas has re-released recently). The Airslide 4180 was actually developed by BLMA (albeit never produced). Atlas carried the project through to completion after acquiring the BLMA product line.
I thought the hopper looked like one of the old Walthers cars?
That's right, now I kind of remember the pre announcement, they had a proto picture that was blocked out, kind of the mystery game that they use play.
LOL, yes they do. There are a lot of different types of hoppers.
I'm certainly no expert on prototype freight cars, but you're right, these are pretty much the same design.
The Atlas (BLMA) car is PS-4000 covered hopper.
The Atlas (Walthers) is PS-4427 covered hopper.
PS = Pullman Standard
The number is the cubic foot capacity of the car.
As for the main spotting differences, the 4000 has a series of round hatches on the rood, whereas the 4427 has trough hatches down the center.
What I was saying was about the details, look at the thickness of the moldings, the ladders and foot stirrups mainly.
The BLMA cars have much finer moldings.
Apparently Atlas is also re-releasing the old Walthers 45 Logging Flat cars and 41' Ballast Hopper Cars. They are all over ebay right now, but from the paint schemes it's hard to tell if Atlas is actually re-releasing them or if they maybe got a bunch of unsold stock from Walthers and are just releasing it under their own name, now.
Atlas purchased the tooling for the Walthers line of N scale rolling stock and locomotives last year. They are now manufacturing these models themselves (well, via China).
