Stacking column across 3d numpy array

How can I stack 2 arrays of shape (1 , 1024, 3) (1024, 616, 3) column wise? For the above example resultant array should be (1025,616,3).

I was able to stack same shaped arrays (1, 1024, 3) (1024, 1024, 3) using

 np.concatenate((x_cache,tile),axis=0)   or   np.vstack(x_cache,tile)    

However I am unable to stack when the 2 arrays 2nd dimensions don't match. Similarly How can I do row stacking when the shape doesn't match.
