Black jack traction engine

Here is screen shot from test ring for my next project.


It will be slightly more powerful version of heavy traction engine with little bigger trailers.

Looking good.  Is it based on anything in particular?  My two traction engines were fairly generic types.

Some progress with project.

Piece and cooled goods trailers are ready and was wondering if those bulk cargo images are textures or hand drawn.

I used Fowler B4 as inspiration for graphics. http://www.steam-up.co.uk/fowler/fowler_bh6971.htm

btw there are 2 carts in svn with intro year 13750 http://simutrans.svn.sourceforge.net/viewvc/simutrans/pak128.Britain/bus/carts.dat

Nice work.  The bulk cargo images are rendered from blender (as is just about everything else, with some minor exceptions).  If you are using blender and want any of the parts I used, just ask and I can send you the blender files.

Thanks for the cart bug report.  I'm sure someone has reported that before, but obviously I never got round to fixing it!

New livestock trailer.

Those trailers look a little large, but otherwise good.  Here is a blend file for a bulk wagon:

Looking good.  :)

Not sure what's happened in the re-rendering, but the wheels on the engine look different now to in the earlier pictures - they all have really black wheels now which doesn't looko so good IMHO.  Apart from that, excellent!

Here is updated version with bulk wagon.

not much of difference but still...

I have tested this in game and I have some comments before inclusion in official releases:

1) Size: both engine and trailer look too large in comparison with existing engines - see attached screenshot.
2) I think power and capacity are over-rated at present for game balance.  I'd suggest reducing power closer to the large traction engine, and the capacity of each trailer to 8.

Yes it is bigger and more powerful than heavy traction engine(that was the idea).
I did some testing and think it would be ok with 10ton wagons 14Kw and intro date 1891.

Those values would be consistent with other traction engines.

         year     max load   speed      power    weight
LTE     1857    6t             15Km/h   6KW       5t
HTE    1876    12t            20Km/h   9KW       7t
BJ      1891    20t            22Km/h   14Kw      11t

All feedback welcome also for how should I name these on final version.

I know it is supposed to be larger than the existing Heavy Traction Engine, but it is noticably larger than even some of the trucks and buses.  I recommend scaling it down.

Are you basing your data on anything in particular?  The heavy traction engine was already intended to cover the more powerful end of the traction engine range, rather than mid-range...

It is based on that machine
http://www.steam-up.co.uk/fowler/fowler_bh6971.htm
It is Fowler B4 type engine. Stated power 8 nhp. 1nhp should be equal to about 3 - 4 KW.
There is little actual performance data for these and I have no idea how fast these did go.

Most powerful traction engine I have seen has stated power of 310hp. Constructed by Ottomeyer, Germany in 1958.

Fair enough then, I think the powers can stay.  But I'd still rather the graphics were smaller (not as small as the existing engines, but much closer to that size).

Do you think that engine should be shorter or just thinner?
I will make wagons 20% smaller later today or tomorrow.

Re: Black jack traction engine

Probably scale the whole thing down - 20% sounds reasonable.  The proportions are good, just a bit super-size!

Re: Black jack traction engine

Now it is ~20% smaller.

That's better.  Is there a download?
