At the risk of being pedantic the S-Bahn in Munich schedules 30 trains

I have commuted for short periods on the Munchen U-bahn and S-bahn and
was very familiar with it, although I've not been there in a while to
seriously use it apart from the airport links.
Nowhere on the Mch S-bahn stammstrecke (the core section) are there
junctions of any sort on the twin track core - only at the ends. The
equivallent scenario for Thameslink is no junctions at all anywhere
between West Hampstead and Blackfriars *and* to make the analogy
correct both of those locations would have to have 4 each dedicated TL
platforms.
On top of that, Mch S-bahn is equipped with LZB.
AFAIK this is unique
among German S-bahn lines ... Mch Pasing to Mch Ost was equipped for
LZB operation from 12/2004 ... IIRC it was set up for 28 TPH although
might have been tweaked since.
For those who do not know, LZB ''Linienzugbeeinflussung'' generically
is a transmission based train control signal system. It exists in
several forms on both very high speed lines and dense close headway
metro lines ... no lineside signals, cab signals only, and operates
by setting target points based on location of preceding train or state
of the ''guideway''.
I am loathe to post a wikipedia link but this is about the only
overview I know of (in German but you can wiki translate it)
http://de.wikipedia.org/wiki/Linienzugbeeinflussung
AFAIW such grandiose signalling systems do not form part of Thameslink
Program ... it will retain conventional trackside aspects with TPWS
and AWS. ISTR Roger Ford referred to this in MR a couple of years back
(although things might have moved since then).
If I thought Thameslink was getting LZB then I'd not have made the
remarks I did.
BTW ... the Jubilee (and Northern, Piccadilly) line signals upgrade is
to LZB ... Seltrac S40 is an LZB ... it even says LZB on the processor
