A little relativistic question.

A ten-meter-long wagon travels on a railway track at Vo=0.8c.

From the front of the wagon, towards the rear, a sends a light signal.

In the wagon repository, the light signal puts To=d/c=10/3.10^8=33.333
nanoseconds.

<http://news2.nemoweb.net/jntp?pbZCc1U8w0Q-53Ha1Of1R8gTV54@jntp/Data.Media:2>

How long To' in R', referential of the way?

<http://news2.nemoweb.net/jntp?pbZCc1U8w0Q-53Ha1Of1R8gTV54@jntp/Data.Media:1>

There are no 'a' sends... perhaps you meant that the front of the wagon sends...

In the wagon *frame*...

As the value of the clock at the front reads zero it sends a light signal.
The back wagon will receive this signal as its clock indicates
the value of d/c = 33.333 ns.

IOW, in the train frame it took a time interval of 33.33 - 0 = 33.333 ns to go from front to back.

> How long To' in R', referential of the way?

Gibberish, not English.
To' and R' have yet to be defined. Learn to write clearly and in a self sustained way.

Fortunately, we have GPS now, so anyone can check that this
insane bullshit is just some insane bullshit.
