Need Help about train fuel automatisation

[Avoltance]

Hi !
I started playing Factorio there is 4 days, and I love it. In game, I want to give fuel (I use Solid Fuel) to a train with 2 diesel locomotive.
I post an image in the next post.
I tried all inserters I had, with chest, with belt, but the inserters don't want to work. Also, I tried to do the same thing that train tutorial learned me, but still not work.
What did I do wrong ?

[impetus maximus]

inserters for fueling trains got broken with update 0.15.7
devs are aware, and are going to be putting out a fix ASAP.
prob within a couple of hours.
