I was just wondering whether the Chiltern Railways DMUs are expected to stop at illuminated rail gap indicators or not.
At first glance, you'd think 'surely not' (or I would) - since the Chiltern trains are diesel units and don't require to draw traction current from the rails. Therefore they'll be unaffected by the loss of traction current in the section ahead.
However, traction current is often discharged for a reason and I think I'm right in saying that that reason is occasionally to ensure that trains are stopped. There may very well be other reasons, too, which could mean that it would be preferable for trains not to enter sections where traction current has been lost if possible. Additionally, illuminated rail gap indicators are, of course, three red lights and red lights are not normally to be passed if it can be helped.
So I was just wondering if there were any special instructions regarding rail gap indicators for the Chiltern trains, or do they just sail past them, paying them no heed?
