I've no hesitation in welcoming any realistic scheme to get the Wealden route back into full use. BML2 clearly goes far beyond the basic re-opening now proposed by Railfuture, and if adopted, would obviously not appear in finished form overnight, so yes - getting the missing miles in Sussex re-instated is the vital precursor to any full reopening. That's regarded as a logical starting point fo BML2 also, albeit with emphasis on earlier redoubling than RF's scheme, and with electrification and the Tun Wells line far higher up the agenda.
Quite what the objection to any group proposing improvements on whatever scale is, I'm less clear about. Those cited by OxtedL as being in a better position to formulate policy haven't exactly inspired confidence when it comes to the Sussex rail network over past decades. If this is finally changing, great - but please don't deride those who've campaigned for years to keep the issue alive, and don't expect anyone to take their foot off the gas until the scope and nature of the new NR study becomes clear.
Regarding the relevance of the route to Brighton passengers, note that this issue is right there in the initial government release, not from a member of WLC, but from Richard Eccles, Network Rail director of network strategy and planning.

As for BML2 being a sledgehammer to crack a walnut, that may properly be applicable to just the issue of a few miles of missing formation, indeed
that IS simple - for a 2tph capacity route (which isn't the final condition envisaged by Railfuture according to their website), however for reasons I've already stated in earlier posts, when looking at the wider picture I'd have to say that it's much bigger than the proverbial walnut. The charge of a solution looking for a problem is a nice soundbite, but presupposes that the problems identified merely came into being as a direct result of the BML2 proposal. I certainly don't view the scheme as a universal panacea, but regard critisism that it attempts best fit solution for as much as possible as a peculiar objection. I'd also add that anyone who imagines that investment in the initial phase of RF's incremental scheme represents the sum total of expenditure required obviously hasn't read their proposal thoroughly.
The demographic of the rail market has changed greatly since the demise of the through Wealden route, and there is much catching up required following on from decades of gradual decline. The rail network needs to develop to reflect this. Railfuture concede that developing services beyond 2tph is contingent on NR's as yet unpublished proposals for East Croydon. This leaves little scope for improvement for a protracted period, and in this, both it and BML2 require infrastructure not yet in place to come to fruition, so don't forget to keep that in mind as it's a charge applicable to both schemes at EC, but seemingly levelled solely at BML2.
If some find the idea of a successful and expanding rail network a tough concept to accept, that's understandable. We've pretty much all grown up used to the railways fighting a rearguard action. With acknowledgement from government growing for some time now that rail has a vital role to fulfill in future prosperity, the idea of the industry in unending decline as an outmoded relic implicit in Beeching and Serpell is finally behind us.
