This morning

The train is stopped!!
It is hard from morning :(

Hi Hitomi, 

I assume you want to say that train services are disrupted, and it is hard to travel around since morning?

Correction:

The train services are disrupted and it is difficult to travel around since morning. 

(We use "since" for a duration that started from a particular time. Example: It has been raining since 8 a.m.)

Hope this helps.
Cheers, Lance

This morning

The train is has stopped!!    Or. The train stopped working.
It is hard from morning :(  <----- NO never say that. That's not an expression. That might be in Japanese but does not translate to English.

What you would say;

It has been a bad day so far.  For starters the train stopped working.....  ( or )

Today didn't start off well, the train wasn't working so I was late.
