March 15th - Public Transportation in Tokyo. March 15th - Public Transportation in Tokyo.

I'm going to talk about the public transportation in Tokyo.

Nothing is grammatically wrong with this sentence, but it's unnatural to start a piece of writing like this. You can put the topic in the title like I did, or you can just leave it out entirely and it will be fine.

Tokyo is one of the world's largest cities, and it has dense, ampleefficient, and complex train lines. Tokyo is one of the world's largest cities, and it has dense, efficient, and complex train lines.

“Efficient” may be a better suited word to describe the functional or serviceable characteristics of the transportation system :D

Tokyo is one of the world's largest cities, and it has dense, ample,a robust and complex system of train lines. Tokyo is one of the world's largest cities, and it has a robust and complex system of train lines.

Again, nothing technically wrong with what you wrote, but it sounds slightly unnatural.

Tokyo is one of the world's largest cities, and it has dense, ample, and complexa comprehensive network of train lines. Tokyo is one of the world's largest cities, and it has a comprehensive network of train lines.

Dense, ample and complex sound odd when describing train lines.

Tokyo is one of the world's largest cities, and it has dense, amplerobust, and complex train lines. Tokyo is one of the world's largest cities and it has dense, robust, and complex train lines.

Here “ample” sounds a little out of place. “Dense” and “complex” give the sense the infrastructure is grand and expansive. But “ample” is more for noting there is a sufficient amount of something. Replaced with “robust” to match the heft of the other adjectives.

They are very useful so that you can reach almost anywhere in the city by train. They are very useful that you can reach almost anywhere in the city by train.

They are very useful so that; you can reach almost anywhere in the city by train. They are very useful; you can reach almost anywhere in the city by train.

Using "so that" here implies that the train lines being useful is what causes the fact that you can go almost anywhere using the trains. It's more natural to say the other way around; you can reach almost anywhere in the city by train, so that's why they are very useful. Use a semicolon here to link the two clauses without using connecting words.

They are very useful soin that you can reach almost anywhere in the city by train. They are very useful in that you can reach almost anywhere in the city by train.

They are veryso useful so that you can reach almost anywhere in the city by train. They are so useful that you can reach almost anywhere in the city by train.

“Very useful so” sounds a little unnatural.

They are very useful so that, you can reach almost anywhere in the city by train. They are very useful, you can reach almost anywhere in the city by train.

However, there are proublems happen on a day-to-daon a daily basis. or, However, troubles arise on a daily basis. However, there are problems on a daily basis. or, However, troubles arise on a daily basis.

"Troubles happen" is understandable but not a very natural phrase.

However, tproublems happen on a day-to-day basis. However, problems happen on a day-to-day basis.

However, troubles happen on a day-to-day basishere can be troubles during daily use. However, there can be troubles during daily use.

This sentence was open to interpretation. In my correction, I tried to phrase it in the way I thought you meant, but I may have been mistaken.

When I arrived at my closest train station, I found out that an accident had been happeninged on the train line. When I arrived at my closest train station, I found out that an accident had happened on the train line.

The original sentence is technically correct, but this suggested edit makes it sound more natural. Accidents are not often referred to with the progressive verb tense (“-ing”) form. The simple past tense “happened” or the perfect past tense “had happened” are more common verb forms used in the context of accidents.

When I arrived at my closthe nearest train station, I found that an accident had been happeninged on the train line. When I arrived at the nearest train station, I found that an accident had happened on the train line.

We rarely use the past progressive tense to describe accidents. Usually an accident is something that happens in an instant, like getting in a car crash or dropping something fragile. You can use the past progressive if you name a specific problem. "The trains had been running behind" "They had been having trouble with the engine"

When I arrived at my closest train station, I found that an accident had been happeningoccurred on the train line. When I arrived at my train station, I found that an accident had occurred on the train line.

When I arrived at my closest train station to board the train, I found that an accident had been happeninged on the train line. When I arrived at my train station to board the train, I found that an accident had happened on the train line.

“Arrived at my closest train station” could mean you were already on the train, and you found out about the accident when you reached a station. I assume you mean you hadn’t yet boarded a train.

When I arrived at my closest train station, I found that an accident had been happeningthere had been an accident on the train line. When I arrived at my closest train station, I found that there had been an accident on the train line.

This one is a little tricky, because it’s technically correct, but it sounds a little odd. Even if the accident is still on going, it’s common to just refer to it as “there was an accident”, or “there has been an incident”. I actually talked with some friends about this and we all thought it was a little odd we never talk about incidents “happening”. Either have or haven’t happened!

I had to wait about an hour for it to resume working, spendingand I spent the time drinking coffee in the cafe. I had to wait about an hour for it to resume working, and I spent the time drinking coffee in the cafe.

Using the phrasing with the definite article “the” with time in “spent the time” makes it a bit clearer that this time you are referring to is the hour you had to spend waiting.

I had to wait about an hour for it to resume working,. I spendingt the time drinking coffee in the cafe. I had to wait about an hour for it to resume working. I spent the time drinking coffee in the cafe.

I had to wait about an hour for it to resume working, spending time drinking coffee in thea cafe. I had to wait about an hour for it to resume working, spending time drinking coffee in a cafe.
