Let's solve this step by step:

1. Let's assume the initial train fare is 3x and the initial bus fare is 4x.

2. According to the problem, the train fare increases by 20%. So, the new train fare is 3x + 20% of 3x = 3x + 0.6x = 3.6x.

3. Similarly, the bus fare increases by 30%. So, the new bus fare is 4x + 30% of 4x = 4x + 1.2x = 5.2x.

4. Now, we need to find the ratio of the new train fare to the new bus fare. This is 3.6x : 5.2x.

5. To simplify this ratio, we can divide both sides by the common factor, which is 0.4x. Doing this gives us 9 : 13.

So, the ratio of the revised train fare to the revised bus fare is 9 : 13. Therefore, the correct answer is 9 : 13.
