Mr. Keane, I have provided the directions you requested from the railway station to the City Hospital Renal Unit. Exit

The directions from the railway station to the City Hospital Renal Unit are as follows:

1. Exit the railway station through the main entrance. This is the main exit that most people use when leaving the station.

2. Once outside, you will find yourself on Station Street. This is the street that the railway station is located on.

3. Proceed along Station Street for approximately 100 meters. You can measure this distance by looking for landmarks or using a measuring device, like a measuring tape or smartphone app.

4. After walking for about 100 meters, you will reach a bus stop. This is where buses pick up and drop off passengers.

5. At the bus stop, you should take a left turn. This means that you have to turn in the direction that is opposite to your right hand.

6. Now you are on the correct path towards the City Hospital Renal Unit. You should continue walking in the direction you turned, following the road or path ahead.

7. As you walk, you may want to keep an eye out for signs or landmarks that indicate you are going in the right direction. If you see signs pointing towards the City Hospital or if you come across known landmarks, you can be more confident in your route.

8. Continue walking until you reach the City Hospital Renal Unit. This may take some time depending on your walking speed and any obstacles you may encounter along the way.

It is important to note that these directions are based on the information provided in the task. If there are additional details or specific instructions that need to be considered, please let me know and I will be happy to assist you further.
