Layton City is still my only City that used heavy rail as part of the commuter transit system. All my other cities either use a combination of subway and elevated light rail, trams and/or busses with heavy rail relegated to inter-city movements.
Consequently there are four heavy rail lines that run either around or through Layton City all of which pass through the City Central Interchange in the City Centre. The four Lines are:
Layton Metro #1 and #2: this is the circular line that around the City in either a clockwise or anti clockwise motion. The Line colours are yellow or white
Onehunga Line: This line runs from Olive Park in the South and runs north through the middle of the City before coming to its major interchange in Onehunga. The Line continues and joins Metro Lines #1 and #2 at Beech District before terminating at Onehunga Central. The Line colour is blue
Manukau to Airport Line (that is Layton City International Airport). This Line starts at Manukau Interchange and follows Metro Lines #1 and #2 north until after the East-West Canal where the Line turns right linking up with the Space Elevator, Stadium Park, City Central and finally terminating at the Airport.
I will post the other Lines later on. But today Metro Line #2 (City Central to Manukau and back around to City Central going in a clockwise direction if looking from the south:
The release of the Mass Transit DLC caused a few hiccups for my establish Cities in Cities Skylines. While I got San Solarian City fixed up quickly my flagship Layton City was more troublesome.
The problem was two-fold:
Old subway stations needed replacing
An array issue meant the game stalled
Replacing the subway stations (and for that matter having to redraw a heavy rail route) was slow but easier of the two tasks. The array issue (mechanics were beyond the capability of the simulation engine) was something else as the issue could only be “fixed” when the simulation pause. That said after some checking on the Forums it was a simple case of “CLEAR TRAFFIC” which clears the traffic off the roads and starts the simulation again from that point. Given it was a Saturday (industry is offline) it was easier to have the reset done.
And from there Layton City is working again and I am reminded I have to fix up the bus and tram routes cause it looks worse than Auckland right now…..
So here is some aerial shots of Layton City in the day and night:
And the night shots:
Good to have the City back. Not so fun going to sort the routes all out when the Transport Lines Manager is poked!
Power is a serious business for a large city such as Layton City. Placement of power plants also matters too as the tsunami saga showed when the City Centre was “cleaned” but the power plants were missed. In Layton City nearly two-thirds of its power is produced by non-Green House Gas emitting power plants with nuclear taking the lead.
Unfortunately a quirk in the game means you need incinerators for rubbish as your landfills do fill up and need to be emptied some how. However, and rather fortunately the main Layton City recycling plant recycles about 50% of the City’s trash lessening the need for incinerators. That said those incinerators still produce 17% of the City’s power so at least not all is lost.
Below is a pie chart of Layton City’s power production:
As you can see the City’s four nuclear reactors produce 56% or some 1.92GW/h of total power with gas next in at 20%. The topography of Layton City rules out hydro but a large ocean means I can increase off-shore wind production. There is plenty of capacity in the incinerators so no new ones will be built for a long time even on current growth projections.
However, the demand load is at 90% of total power production so I will be needing a new power plant to be built soon. The question is what. I am most likely to build a new nuclear power station in the inland area of the City away from the Tsunami prone City Centre. While the new nuke plant would take its share to about 65% (meaning clean energy goes to 73% total) gas still forms a large part of energy production. Location of the gas plant is also a factor as it is next door to the energy intensive ore production complex decommissioning the power plant is not straight forward even replacing it with nuclear (becomes expensive to commission two plants back to back). That said the plant will be eventually replaced.
Heating wise Layton City is a temperate climate like Auckland so it can get cold at night. Heating using electricity would tax the power plants that are already at 90% as well as being straight inefficient. So I use a central heating system that covers about 60% of the City (still need to retrofit the historic parts) that draws on geothermal energy – aka natural steam.
Currently 640MW/H of electricity production is saved through the geothermal heating system (load is at 85% capacity) when it gets nippy at night. I prefer using geothermal over oil boilers for both cost and emissions (or lack thereof). Eventually I will get around to retrofitting the historic districts with central heating.
Here are some pictures of power and heat production in Layton City
As for cutting emissions down further? Time to improve the transit system.
Well Christmas for Layton City got a tad wet and windy after a freak storm rolled through the City causing mass flooding and even a tornado.
The Imperial Management of Emergencies Agency reported that a EF1 tornado had touched down south of Onehunga and proceeded west through open country before dissipating near Layton City International Airport. However, the severe rains accompanying the tornado had caused mass flooding in the east with the storm water systems unable to cope.
Weather Observation analyst Bill Duncan said storms were not uncommon in Layton City as the Summer rolled on with a few producing a few tornadoes usually out to sea (Waterspouts). Having one touch down on land is unusual however, the Civil Defence system by IMEA worked as it was meant to. Of course the flooding in the east will need to be dealt with after the Foggy Heights Canal again breached its walls causing flooding in Evergreen Heights and Orchard Square.
Layton City Department of Transport reported that minimal damage to infrastructure was reported with a rail line and section of State Highway 20 damaged by the tornado but quickly repaired.
Citizens are hoping the rest of the Summer holidays are not as intense as the Christmas Day tornado. I think we can all count ourselves lucky the sucker missed the airport by mere metres.
Okay first lesson with the Tsunami, ONLY HIT THE BUTTON ONCE! The cool down timer and the arrival of the wave does take a long time as in towards six hours of game time being simulated. I accidentally hit the button twice and got a double tsunami which in real life does happen depending on the quake and amount of wave trains it generates.
Early Warning System works
As part of the IMEA (Imperial Management of Emergencies Agency) planning I had laid out a network of Tsunami buoys to detect any waves while deploying radio masts City-wide to give out early warning alerts.
Sure enough while I was checking out the City Centre as it was a weekend afternoon meaning LOTS of shoppers and tourists the buoys picked up a wave (well two) and the radio masts started sending out the alerts.
So I trigger the evacuation systems and you hear the wailing of sirens across the City alerting people to head to the bunkers – apparently.
People really didn’t start moving until the wave was beginning to break over the sea walls THEN people started moving. Remember I have capacity for 172,000 in a city of 242,000!
The double wave started its trip through the City Centre, Downtown, Airport and Newmarket before heading up one of the rivers meeting the wave from a second entrance.
The result? Surf’s up:
Included is the disaster response which was extremely prompt with the choppers and later the trucks when the water cleared.
How far would the Tsunami go?
What I was interested to see and equally afraid of was how far would the wave travel up an estuary on one side and the west coast on the other. The estuary is a threat as it leads to the main industrial complex and both nuclear power stations that power the City. The western coast that feeds into another estuary leads to the main airport and to Manukau City Centre and its industrial complex.
The western coast got hammered and it wasnt until the wave met some canal walls that were part of the storm water drainage system did the wave’s reach begin to dissipate. As for the estuary the wave travelled up the waterway causing moderate flooding along the shore. The wave did manage to travel far enough upstream to have the wave reach one of the nuclear plants but only cause very minor flooding. The wave totally faded out before reaching the port while also dissipating well before it could hit Manukau.
The western side
120,000 people were in the bunkers while 22,000 out of 242,000 were killed in the double Tsunami (9% loss). The City Centre and Downtown were hit but Newmarket which houses the leisure district was effectively wiped out.
The IMEA response teams were prompt and I was able to release the Citizens from the bunkers a short while later.
Infrastructure was hit with subway stations, power transmission, parks, emergency services and schools taken out but thanks to IMEA being fast restoration of those services was prompt.
By morning the damage could be very easily seen. Newmarket looked like it had a bomb go through it while the City Centre and Downtown also took some damage mainly to infrastructure. The IMEA response units had been through all the infrastructure facilities meaning I could rebuild them very quickly. While with the urban development side about 85% had been seen too and could start rebuilding.
Priority was to get the crematoriums, fire stations and stations back open to avoid a secondary disaster and get the flow of goods and people moving fast.
Once they were built I went back to get everything else.
There were several factors that helped Layton City through a double Tsunami with 9% loss of lives. Yes we had the buoys, masts, bunkers and IMEA but things like the storm water infrastructure was able to pump out the flood waters very fast meaning water was not lingering.
The main industrial complex was never touched as wasn’t one of the nuclear power stations (the other was but very minor flooding that did not cause the reactors to SCRAM). The main water and sewer pumps were also not affected either so the emergency tanks were not needed this time around.
So with main power and water still available the City was able to function (although limited until the infrastructure was fixed) and the industrial complex providing materials for the rebuild.
Busses and heavy rail proved to be the most resilient in the disaster. Once the waves have swept through the busses began operating again straight away with freight and passenger trains not far behind. The subways and tram lines did need extensive rebuilds before they were operational again.
But it shows the resilience in transit modes especially after a disaster. The busses and trains were able to move thousands of evacuated people back home (unless their home was destroyed and a night in the bunkers) while freight trains moved goods and materials to their cargo hubs as part of the rebuild effort.
Evacuated citizens waiting for the trains back to the City Centre after the Tsunami
Already people are moving back and homes and businesses will be rebuilt. Layton City did extremely well with the disaster and its subsequent response. But heck citizens were slow to the bunkers. Next time let’s try to get a few more people there.
So I got the Natural Disasters DLC for Cities Skylines. Once the mods were updated by their developers (to my massive thanks) I was able to load up Layton City (my grand city of 243,000 which is HUGE for Cities Skylines) and give the new DLC a whirl.
Now I do have the Rainfall mod that properly simulates rain and storm events which means run off and managing storm water effects. This means inlets, detention basins, outlets and pumps throughout the city to move the storm water. So events that trigger flooding like storms, tornadoes and the Tsunami will have their dynamics alters compared to NOT having the rainfall mod.
Preparing for disaster
So before letting a disaster rip (including sodding forest fires that spawn off every time the Rainfall mod lets loose a storm) we need to place down some disaster management items.
Radio towers, sensors (earthquake and tsunami), Deep Space Radar, Weather Radar, fire watch towers, bunkers, disaster response buildings, helicopter depots for fire, medical and police, water storage tanks and a depot to send out vacuum trucks to suck up flood waters. All needing to be placed and strategically.
I decided to create three centralised disaster response management centres that each have enough bunker capacity for 120,000 people. Scatter some more bunkers around the city and we have capacity for 170,000 out of 243,000. Of course police and fire helicopter depots are more scattered around the City for various reasons.
Post disaster the three disaster response centres (Imperial Management of Emergencies Agency) in total can deploy 12 search and rescue helicopters as well as 40 ground units. The IMEA’s were already tested with two small urban forest fires popping up that had caused destruction to some of the urban area. I was quite pleased in the responses and the pace of the rebuild.
So I thought given Layton City is a coastal city how about letting a Tsunami rip? Well I did with very interesting results. Needless to say the three IMEA Centres worked brilliantly as did a stroke of planning brilliance.
Layton City is powered by four nuclear reactors and a two-unit gas-fired power station. Given Fukushima I did wonder how the nuclear stations would cope with the Tsunami in Layton City. Would the City suffer 95% losses as other Cities Skylines cities have with the 1-2 Tsunami – nuclear knock out?
Well you will see in the next post as well as the disaster recovery operation (and why rail is king).
In the meantime some photos in the lead up to the Great Layton City Tsunami Disaster:
