Denuwara Manike Train - Sri Lanka (දෙනුවර මැණිකේ දුම්රිය - ශ්‍රී ලංකාව)

This video is about Denuwara Manike train, which is the newest addition to Sri Lanka railways on late 2019 and was put to service on 1st of November 2019. Currently it is the fastest way to go to Badulla by train. This intercity express train known by train number 1001 will depart Colombo Fort railway station every other day at 6:45 AM and reach Badulla station at 3:30 PM after stopping at 11 stations on the main line. On the next day it will be train number 1002 and will return at 7:20 AM from Badulla station and reach Colombo Fort station at 4:30 PM, after stopping at 12 stations, making a journey of 294.3 kilometres in about 9 hours. Train will stop at Polgahawela, Peradeneya Junction, Gampola, Nawalapitiya, Hatton, Thalawakaelae, Nanuoya, Haputalae, Diyathalawa, Bandarawela, Ella. On the way back it will stop at Maradhana additionally.

Train consists of 2 Air Conditioned first class compartments with adjustable seats, adjustable arm rests, individual tables, television screens, audio jack ports, foot rests, cup holders, seat back pockets, 240 volts power outlets for some seats. 2 second class compartments with adjustable seats, adjustable arm rests, individual tables, foot rests, cup holders, seat back pockets, openable windows, 3 third class compartments, a restaurant car with disabled toilet facilities and 2 identical engines in the front and back with fully air conditioned driver and guard rooms. All compartments are having train information display screens, music, fans, luggage holders and toilets with sinks.
Denuwara Manike has a spacious disabled toilet in the restaurant compartment. Normally the door of this is locked and the restaurant staff got a key for this. It is having automatic door and hand rails for easy access. Good size sink and a mirror is also available. There is a small cubicle with a mirror and a sink near the disabled toilet for public use.

These types of trains are called DMUs which stands for Diesel Multiple Units. This S14 type powerset was manufactured by China Railway Rollingstock Corporation and was purchased for 1845 million rupees. Each of the two 11-cylinder engines can supply 1500 kilowatts to the train through AC – DC power transmission system and they are connected using the train’s electricity system. They are numbered as engine 971 and engine 972 by Sri Lanka railways department. In an engine failure, the train can reach its destination with one operating engine.

For the first time in Sri Lanka this train has a camera system and a Blackbox similar to aircraft Blackbox and records and stores all the operational data with the front camera view. The train information display screen, on this train is made out of LED panel which will display train running information in all 3 languages Sinhala, Tamil and English. It will display information such as train name, number, start and end station names, speed, next stopping station. Engines also got fuel tanks capable of storing 3500 litres of Diesel. Maximum possible speed of the train is 120 kilometres per hour. In the daily run between Colombo and Badulla it reaches 90 kilometres per hour in some sections of the route. To make the ride extra smooth, these carriages are fitted with air suspension system rather than the conventional suspension systems.

Train’s braking system is made by a German company named Knorr-Bremse, who are renowned for manufacturing reliable braking systems especially suited for hill country trains.

Since the train got 2 engines in the front and back, it doesn’t have an observation compartment.

Full route fair for first class is 1700 Sri Lankan rupees, second class is 1000 rupees and 700 rupees for third class. This train will only accept passengers who have booked tickets prior, so you cannot just buy a ticket from a railway station and get in. Tickets can be booked from most of the major railway stations like Colombo Fort, Maradhana, Badulla, Ella, Kandy, Hatton, Mathara, Galle, Anuradhapura, Jaffna.

Little Crystal Creek Falls, Crystal Creek, Queensland, Australia

Another interesting waterfall in Queensland is the Little Crystal Creek falls in Crystal Creek. This is made out of 2 to 3 small cascades of water and a pool of water.
This waterfall is located about 75 kilometres North West of Townsville and is reachable in a hour of driving. The road is bit winding after turning from Bruce highway. But it is sealed all the way so a two wheel drive small car would take you there without any problems. When driving from Townsville there is a big car park about 200 metres before the bridge to the left. It can easily accommodate 15 cars so you do not have to worry about finding parking.
At the park there will be 2 boards with maps and details about the area. To reach the waterfall, you need to walk about 150 metres towards the arch bridge from the car park. The bridge is a 18.3 metre long bridge constructed in 1932. There is no separate path but can walk on the left side of the road so be careful if you are travelling with children. You can reach the bridge with a pram or a wheelchair and have a look at the waterfall. But to go anywhere near the water you need to walk down the stairs and some walking on the rocks depending on the side you start walking down. I would say it is an easy 15 minutes walk from the car park. Also you can reach the waterfall starting from any side of the bridge giving you different views of the nature, so you can start from one side and come up from another.
Once you walk down you will be able to see the creek. In the dry season there will be not much water so it will be safe to walk besides the water. Near the bridge there is a table and a bench to sit and relax and have a picnic near the water. Near the car park there are barbecue, toilet and waste disposal facilities as well as a park for children to run around so I would recommend enjoying some food over there.

The actual error is given in the inner fault section, the same error is logged in the event log of the CRM server as below.
Exception information:

After a while found the “Complex Control” privileges are listed as “Process Configuration” in CRM security roles. To fix the issue go to CRM Security Roles and open Customization tab. There you will find Process Configuration for which you need to provide Read permission. 

Giving permissions according to the error you see will fix the issue, for example if your error showed your were missing prvCreateComplexControl, then you need to provide Create permissions.
More details about security role UI and privilege mapping can be obtained from the Microsoft article.

Unable to Enlist in the Transaction

I recently received an error while trying to run a SSIS package in Visual Studio. The full error is seen as below.

Error: The SSIS Runtime has failed to enlist the OLE DB connection in a distributed transaction with error 0x8004D024 "The transaction manager has disabled its support for remote/network transactions.".

This error is happening when a component with transactions try to connect and manipulate data on a remote server.

To avoid this error, two things can be done.

* Remove the transaction handling from the component. – This should be done only if the transactions are not required or as a temporary measure.

You can do this by selecting the properties of the component, also check the package properties to make sure transactions are not enabled at the package level.

For an explanation of the options please visit the URL.

* Configure the Distributed Transaction Coordinator (DTC).

For a component to work correctly with transactions, below two things are required.
1. Running Distributed Transaction Coordinator (DTC) Service

This service should be running on the database server the component connects to and on  the machine where the package is running. This will coordinate the work between two machines / servers.

This can be checked and started by going to Windows Services.

2. Properly configuring the security of DTC.

To make the DTC service work properly, it should be given permission as required. This can be done by opening the Component Services window. In the component services window, navigate to Component Services –> Computers –> My Computer –> Distributed Transaction Coordinator. Right click Local DTC and click on Properties to open properties window.

If you are intending to run any workloads with transactions via any external servers you should enable “Network DTC Access”.

Depending on the situation you should allow Inbound, Outbound or both transaction manager communication options.

For complete list of explanations on each property please refer the following URL.
