Hi Shelton, it will work fine, but you will need two x 24951 Transition sections to join the C track to it.

If you already have the 7390 crossing then of course go ahead but being a purely mechanical crossing it relies on the weight of the train to press down on the outer rails and close the barrier arms. If this happens when the Preiserlings are crossing, it gives them a headache when the barrier arm crashes down on their head and does not make for good Railway Company PR.

Fine for a child's layout, and sometimes even for a display layout but if you are looking for something a little more realistic then you probably want the one that is electrically activated by the train as it approaches.

More expensive of course so that's up to you but the 7390 will work just fine in any event.

Hope this helps

Steve
