IHH Western Packs Released

[anthonye]

I must say that I have never seen support like this from a Payware developer. When I bought the 9F I had a misunderstanding about the brakes, I emailed Sly and he replied with a detailed note on how to do it correctly, and the reply was within half an hour.

I bought the Western tonight and asked about changing the name and numbers, again he replied within the hour with a detailed how-to.
I just emailed him asking a question about the Western Pack and cabs, yes that's right he emailed me back again quickly with the answer.
So now I am going to stop asking and let him get on with making the next loco's, which I will buy seeing the support is like this.

So anyone who is hovering about buying any of the loco's, just do it, you won't regret it.

The Western Region Diesels pack...do the locos have aliased cabs, at least? Or are they like the US Dock tank on Project Platform?

[FoggyMorning]

The external view of the cab is pretty good. Not up to the standards of the Western but very good nonetheless
The Warship and class 14 have a very rough 3D cab model, the Hymek, 22 and Brush Type IV have a cab view but no actual cab model - it's like you're sitting in mid air in front of the train

The Brush is a little odd - Sly's previous version of the 47 has a full cab view (aliased to the default I think?), but this one does not

To be honest, at this point I don't think any of them are locos you are going to want to spend a lot of time driving from the inside. It's not a problem for me - as Sly has stated on the IHH website their primary purpose is to give authentic AI atmosphere to complement the Western, and full cabs will be upcoming in time. And at £20 for 5 locos (+VAT) that's only four quid each, which is very good value in my book

thanks for the info, Steve

I have a possible issue, which may be down to my graphics settings but I don't know. The brake gauges are flashing all the time and the cab seems to rock and roll for no apparent reason. I have just completed the Cardiff scenario and the cab has been rocking all the way through. Apart from that I love both packs.

sounds like the cab shake bug. should sort itself out by next time you play, if not try clearing cache.

With all the hype these received I was highly disappointed that unicorns and rainbows weren't flying out of the exhaust stacks while pushing rollingstock of magic carpets piloted by magical genies and making sacks of gold coins appear in the passengers hands when pulling up to station stops.

I kid, I kid! Good work Sly as usual, I like it a lot. The AI pack is a great little investment into the Railworks savings bank, I look forward to the future interest gained out of them and will enjoy their current AI role.

Thank You

Regarding the physics and permitted power applications...

I believe that full power application from stall is permitted, unlike a typical DE loco, and the most you might need to keep an eye on is the transmission fluid temperature if you feel the need to sustain full power at crawling speeds. For passenger comfort and avoidance of coupling snatch however, a smooth power application would be recommended.

Wheelslip would normally be less than a similar-weight DE loco, because the three axles on each bogie are mechanically connected (using a driveshaft and right-angle gearing, rather than the rod drives found on shunters). It is not totally eliminated - there's a Youtube video somewhere with a rather spectacular sparks-show from what appears to be an impromptu tyre-turning session... but it is certainly much easier to put full tractive effort down than with a 37.

Each bogie is driven by it's own engine and transmission, so if you lose one engine, you'll lose half of normal power AND tractive effort limits, unlike say the Deltic, which would lose only half power. This was due to hydraulic transmissions at the time being incapable of handling Type 4 power levels individually.

As an aside, there is a modern transmission available from Voith which can connect a single large prime mover to two bogies using a separate hydraulic circuit for each bogie. This neatly sidesteps the power limitations of early designs, and they do a few neat tricks with it into the bargain.

What I don't know - not having bought Sly's model (yet) - is whether RailWorks models the power/speed curve reasonably, given that all three circuits on the Western's transmission are torque converters. The results from the existing DH models (two German locos and two British DMUs) are not encouraging.

Another masterpiece by Sly. Lovely model.
Lots of effort has been put into getting realistic sounds. Now distant sounds are pretty good. Maybe track sound is not loud enough but almost everything else works perfectly. Reverse switch without any sound. Cabview very well modelled but I had to adjust drivers position little bit as following:
Cabview: Left side X -0.85 Z 8.2 Right side X 0.77 Z 8.2
Head Out View: Left side X -1.54 Y 3.1 Z 8.26 Right side X 1.54 Y 3.1 Z 8.26
Physics seem to be okay basically. Only one note - power controller don't always add power smoothly enough. Somewhere in the second half power suddenly jumps up on certain one notch. I hope this will be fixed.
I'm very satisfied with this loco model. Sly is a man. He has released so many nice models in a short timeline and some intresting ones are coming soon.

Thanks for clearing that up, its taken a lot of mystery out the operation of the real thing. Ive a reprint of a BR diesel operators manual that has a large cut out of a Western In it, I guess I really ought to brush up on that.

I did think it was accelerating too quickly out of Stapleton road, then I realised it was because I had left half the consist behind in setting the scenario up. What a muppet. After correctly putting 10 on, in comparison to the peak it seemed to accelerate better than that machine, but then it does have 2 engines on it. up a 1 in 300 it was up from 50 to 90 in slightly under 10 miles.

Pulling 20 TTA, it seems realistic in pickup, or at least not provided any surprises. I must try it on the sapperton test to see what its like on a 1 in 60 though....

Incidentally, does anyone know what the speed restriction for braked freight in the 1960s was? 45 just seems a bit tardy. This machine wants to haul MUCH faster than that.

I have a problem with the Sand Class 52. This crashes the sim with a "Failed to Create Vertex Buffer...Line 138" error. The Blue version is ok.

[Drogba11CFC]

75 for Milk, 55-60 for Class C (Fully Fitted), 50 for Class D (50% or Greater fitted), 45 for Class E (20-50% Fitted) and 40 for Class F (<20% Fitted).

I seem to have a problem with the centre set of wheels on the rear bogie jumping up and down from the track on the Cardiff scenario,

all other wheels are fine. Anyone else have this issue?

Something to do with the rear bogie was mentioned on the previous page. Paul has said that a patch will be issued accordingly,

[connorurry]

Just purchased both packs (now donwloading) Can't wait to drive these and make scenarios for them.
