RAILWAY DRAWING

My latest daydream a futuristic freight locomotive still under development

Neat models. I'm not into trains, but I am into airplanes. A minor critique of your freight loco is it's aerodynamic shape at the front end.

Depending on its speed, say anywhere over 90 mph, the rounded nose will create a lift and potentially unload the front bogies enough to be a problem. This lift is more from the ram air effect on the lower part of the nose and not the winglike lift from over the top. My suggestion is to drop the leading edge down closer to the track, more like the loco in your first model in this topic.

Also, what practical purpose is the very aero shape on a freight loco? It won't offer enough anti-drag to pay for its complexity to build considering the amount of aero drag on common freight rolling stock.
I can see such shaping on fast passenger trains, not lumbering freighters.

Sexy shape though.....

Thanks for your comments much appreciated however i did say the project was still under "development" and your comments will go a loooooong way to improve the design

And so the freight train grows.....

The file is now becoming unmanageable so i don't foresee the train getting much bigger

liam887

do they really stack two high in real life!!!! looks like it could be dodgy around corners lol.

dolphus

Thanks for the comments guys
Yes Liam they do stack the containers 2 high and believe it or not automobile 3 high (a future project)
thanks James i would love to do detailed tracks but the enemy is as always polly count.....

For Liam......

As yet unpainted and under development a "Stand alone Well Car"

liam887

Wow thats pretty cool, and cars three high lol!, we dont have trains like that in England!

dolphus

We don't have them in South Africa either but you know what they say "it's always bigger in Texas"

dolphus

Painted and working "Stand Alone Well Car" for moving up to 15 freight containers short distances (approx 20 t0 150 kilometers) and for container delivery, collection and switching

olishea

woah great detail!! what do you use these models for? im just curious!

dolphus

Thanks for the kind comments guys
James i model from plans, photos etc when i can get them and when i feel lazy or "inspired" the fruits of my imagination
olishea i model just for my own amusement and enjoyment

I am moving in a slightly new direction....switching or as it is called here in South Africa "shunting".
The first element required for switching/shunting is switches/points.....

....and of course we need a switcher loco...
The ALCO S4 Switcher
Some interesting statistics about my first switcher
New: 1 May 2005
Weight: 229,700 lbs
Horsepower: 1000
Tractive Effort (starting) 69,000 @ 30% (S-2) and 72,400 lbs @ 30% (S-3)
Tractive Effort (continuous): 29,200 lbs @ 6 mph / 34,000 @ 8 mph
Quantity Built: 1,462 (S-2) / 651 (S-4)

My GE Gas Turbine Loco crossing my first bridge scenery needs tweaking?

alexandre sk

great modeling!!

Here are the first images of my switching yard......
