'I was not going to do something' használata lehetséges?

Ha valaki nem lenne tisztában a jelentéssel (pozitív):

I was going to do something = I intend to do it, but didn't do it.

Tehát pl:

We were going to travel by train, but then we decided to go by car insted.

Szerintem 'I intend to do it' az lehet egy tagadás (Negatív) szándék esetén is, mert az is egy szándék.

We were not going to travel by train.
