[OTTD] NARS Add-on Set 2CC (version -r2218) NOW WITH EMU'S!

Discuss, get help with, or post new graphics for TTDPatch and OpenTTD, using the NewGRF system, here. Graphics for plain TTD also acceptable here.

The 'Service Speed' listed on wikipedia is misleading. The BBD M7,M8 Railcar and M2 were all designed to be used in regular service at 100 mph. In fact, up until five years ago the M2 and M8 Railcar were both used at higher speeds. All three have been reduced to lower max speeds because of the decrepit and still declining state of American infrastructure.

America's infrastructure problems shouldn't matter in OpenTTD where all transport companies diligently pay the property maintenance fee
NekoMaster wrote:100 mph or 163 km/h is a bit too fast for 3rd rail
It's not unusual. Many UK 3rd rail EMUs and their associated NewsGRF have their speeds set to 100 mph. The most prominent one is the Electrostar 3rd rail variant and that's also made by Bombardier.

Can someone verify that sort by Power/Running Cost works right? I seem to be having issues.

It seems like Power/Running Cost won't sort locomotives correctly in the 'New Rail Vehicle' window, 'Available Trains' window, and 'Replace Train' window.

Example:

Version: OpenTTD v1.8.0

GRFs in use:

NARS ADD-ON SET 2CC, -2218

Date: Jan 1st, 1985

Currency: USD

Running cost multiplier: 1x
Purchase cost multiplier: 1x

GE P30CH (Diesel) has a power of 2237kW with a running cost of $33,636/yr

GE U30CG (Diesel) has a power of 2237kW with a running cost of $32,662/yr.

Ranked from largest to smallest (putting most kW/$ on top), the GE P30CH is above the GE U30CG even though the GE U30CG has a lower running cost for the same power and thus should be above the GE U30CH.


This is an example, I only chose those 2 locomotives to illustrate the issue since the equal power outputs makes it easier to do a quick spot check when trying to get GRFs to work together.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Regarding max speeds:


80MPH defiantly seems to be low for the Kawasaki M8 railcar. Kawasaki's own site lists it's max speed as 100 MPH.


The convergence on 128kmh/80 MPH makes me think that there may be influence from FRA track classes at play here.


From the wikipedia article "Rail speed limits in the United States", modified to preserve information since the formatting doesn't carry over, the list of fra track classes is:

Track type Freight train Passenger
Excepted [us 1] <10 mph (16 km/h) not allowed
Class 1 10 mph (16 km/h) 15 mph (24 km/h)
Class 2 25 mph (40 km/h) 30 mph (48 km/h)
Class 3 40 mph (64 km/h) 60 mph (97 km/h)
Class 4 60 mph (97 km/h) 80 mph (129 km/h)
Class 5 80 mph (129 km/h) 90 mph (145 km/h)
Class 6 110 mph (177 km/h) (Freight and passenger)
Class 7 125 mph (201 km/h) (Freight and passenger)
Class 8 160 mph (257 km/h) (Freight and passenger)
Class 9 220 mph (354 km/h). (Freight and passenger)

Conveniently enough:
FRA rules limit track speeds on the corridor to 80 miles per hour (130 km/h) over conventional crossings and 95 miles per hour (153 km/h) over crossings with four-quadrant gates and vehicle detection tied into the signal system. (from Wikipedia article: Northeast_Corridor, section 2.3: Grade_crossings.)

Either way, I'll try to remember to change that next time I update the set which should be soon.
And Jet Train as well.

They'll have about the same tractive effort though, because (given the same production year) they share the same traction motors and almost always weighed roughly the same. This is also true of the EMD SD38/39/40/45 family and others.

Caveat: This mainly applies for the same gear ratio, for different gear ratios the difference between maximum T.E. and continuous T.E. becomes important.
Very true, however in this mod and the NARS mod they short it big time. They only gave it 80,300+ tractive effort when it actually is 91,500 to 92,500 for all of them.
What are you talking about? If I made a mistake with one of the engines let me know. If your going to argue about starting and continueous TE though I just go with what seems to be the norm and using Continuous Tractive Effort (some locomotives have very high starting TE which would make them very cheaty as they would accelerate instantly)
Sorry, I haven't been on in a long time. I was talking about a mistake made with the GE locomotives previously mentioned. The U33C had 92,500 lbs of continuous tractive effort at the "regular" gear ratio of 74:18 which allowed for 70 MPH top speed. The U36C has the same specifications as well. This is using the regular weight on it, not ones with added weight either.

I could give you updated info for all EMD, GE, and Alco/MLW stuff if you wish, some stuff is good already but some does need a bit of work.

I had a look at the buy menu for this, nice work getting it done :)

Does the crane get any use in game? :)

Asking because I’m thinking of adding some eye candy vehicles to Iron Horse, with zero gameplay purpose (crane, snowplough etc). Too much work for too little benefit? :)

I used pikka’s snowplough in NARS maybe in one game only :twisted:
