Decided to add a couple more to this roster, mainly just because I could, but also because it sort of makes historical and technical sense for this scenario (and obviously they are potentially also useful for other scenarios).
The 23 Class, which I made previously, actually came in two orders: 9 units in 1865 (with 69 inch driving wheels) and another 4 units in 1869 (with 66.5 inch driving wheels). The second order was changed slightly (smaller wheels) because the first batch were found to be a bit short of grunt on some of the NSWGR's harder grades. It's not worth having two slightly different versions of the 23 Class in the game, but fortunately there is another class that will do the job nicely.
This is the 10 Class, introduced in 1870, and exhibited in Sydney at the Intercolonial Exhibition of General Industries and Arts. This class was notable for being the first main line locomotives built in Australia. They were a 2-4-0, like the 23 Class, and had 66 driving wheels (fractionally smaller than the second batch of 23's). They also had more heating area than the 23's, which generally increases efficiency, and were recorded as using less coal over the run to Goulburn, while being able to easily keep the same times. So, the 10 Class would make a nice addition to the scenario. It's roughed out already.
I'll set it up so it has slightly lower top speed than the 23 on flat ground, but is a bit better up grades, and a bit cheaper to run. Purchase price will be slightly higher. Maintenance and reliability will be the same.
The other addition is going to be the 20N class, a Kitson 0-6-0 saddle tank that operated on the northern section around Newcastle. This locomotive
still exists as a museum exhibit, and was even in service until 1967. Since it has managed to survive for 150 years, it seems a bit disrespectful to ignore it.
Another of the same class (but built in 1878) also survives. Back in the day, they used to look like this:
This class is already roughed out in Blender too:
As an example of a UK/Euro/World saddle tank, which is something the game doesn't have yet, it should be a nice addition. They were common units worldwide, so I think we should have one. I'll set up the stats so that it makes a good replacement for short haul freight, to take over from the 6N Class in the 1870's.
It will have a similar purchase price but significantly higher fuel cost than the 17 and 93 classes (the other freight units) but much better acceleration, with a high free weight value but a fairly low pulling power (good around Sydney and Newcastle, but no good for the scenario's longer runs).
This will give 12 classes for the NSW scenario, all of which should have a fairly useful niche, and with a new class coming in every few years just for fun and interest. I'll probably fudge a few of the introduction years for more even spacing. The game doesn't let you have a new loco until halfway through the introduction year anyway.
Code: Select all
Class Type Introduced Fudged Gap
-------------------------------------------------------
1 Class 0-4-2 1855 1855 N/A
8 Class 2-2-2WT 1858 1858 3 (Makes sense for Sydney pax traffic)
9 Class 2-2-2 1861 1861 3 (No need earlier + may work for N pax)
6N Class 4-4-0T 1863 1863 2 (NSWGR 1863: unsure if should fudge it)
(Would be good to have earlier, but can last until 1872)
14 Class 2-2-2 1865 1865 2 (Keep the 14, 17 & 23 classes as they were)
17 Class 0-6-0 1865 1865
23 Class 2-4-0 1865 1865
10 Class 2-4-0 1870 1869 4 (NSWGR 1870, but fudge to match 2nd 23 order)
Maintenance/reliability should be equal to 23 Class.
Higher purchase price, cheaper on fuel, a bit less top speed, a bit more grunt.
48 Class 0-6-0ST 1872 1871 2 (NSWGR 1872, but Kitson from 1870)
67 Class 0-6-0T 1875 1874 3 (NSWGR 1875, but LB&SCR from 1872)
79 Class 4-4-0 1877 1876 2 (Fudge 79 & 93 classes, to give 3 solid years of use)
93 Class 0-6-0 1877 1876
I'm also contemplating a general price increase for all of these locomotives, to make it a bit more difficult to spam a stack of them in the NSW scenario. A purchase price increase of 10-20%, and possibly the same on running costs, may be better.
