"The bus is in a station."
Translation:Tha am bus ann an stèisean.
If you mean in order to show the gender then yes I think that is a really good idea. I am not sure including the article is the ideal way as you will see later that different articles are used in different sentences and it would be both tricky and confusing to have different hints for the same word in different sentences. You will need to be able to work out the correct article from the gender and the context.
