Wiatakere Tunnel upgrade for transport link to Kumeu etc.

Graeme Hammonds made this Official Information request to KiwiRail

Currently waiting for a response from KiwiRail, they must respond promptly and normally no later than (details and exceptions).

From: Graeme Hammonds

Dear KiwiRail, I am a committee member of the Kumeu/ Huapai Residents and Ratepayer Association dealing with transport issues. We have been trying for a long time to find the real answers as to why the Waitakere Tunnel can't either be electrified or used for a shuttle train.
With this in mind can you answer the following questions.

1. It has been stated that the tunnel is too narrow or not high enough for electrification. Is this correct could you provide the details including a comparison with the Parnell tunnel which was lowered 35 centimetres to accomodate the electric trains. I can find no details of these tunnels dimensions on the net.
2. We have been told that diesel units cannot use the tunnel because of the safety requirements post Cave Creek. Is this correct and if so can the units be set up with fire protection gear needed to comply?
3.Do you have any reports done on this Waitakere Tunnel that you could supply to us including costings etc. If so could you provide us with them?

We really need to clarify the above so we can inform our Communities .

Yours faithfully, Graeme Hammonds
