I am interested the Railway Clearing House/LNWR block bell codes in use before the Great War and understand these are contained in Appendix B of the Working Time Table, which exists for 1909 in the LNWR society archive. Does anyone know these codes for 1909? Would these be the same as those listed on the society website, or is this a later revised set of block bell codes perhaps from the 1916 Appendix B? Many thanks, Gareth

Gareth,

As you infer, the Block Regulations and bell code used by the LNWR in the period 1902 to 1922 were an adaptation of the RCH "national" code. The RCH bell code was originally implemented in 1884, followed by a full set of Regulations in 1893. The LNWR followed this to a large extent, but with some additions and variations.

The LNWR Block Regulations formed Appendix B, as you say. This was reissued in 1899, 1902, 1905, 1908, 1911 and 1916 as part of the set of Appendices A to U. Additionally there was a reissued book for Appendix B (only?) in Feb 1909. I only have photocopies of the 1905, 1911 and 1916 books. The 1911 issue is marked as a re-issue of the 1909 book. Also as you say, the latter is in the Archive at INSTW 029, but I haven't yet had a chance to compare this against 1905/11.

As an aside, from 1903 the RCH block bell code was aligned with the new RCH headlamp code. Before 1903 there considerable conflict between the RCH bell code and the LNWR headlamp code! And the WTT column headings were aligned with neither!

The bell codes associated with Regulations 6 to 30 were unchanged from 1902 until 1916 at least, but there were a few new ones in 1920 (GM Circular 3085). There were some additions to the "Is line clear?" codes associated with Regulations 3 & 4:
before 1911 (c1909?) - "I L C for Rail Motor Car or Motor Train?" 3 - 1 - 2
after 1911 (3/1914) - "I L C for Stock Train required to run at E P speed?" 3 - 1 - 1
c1915 new category "Goods Trains fitted with vacuum break throughout" included (with NPCCS) in code of 5 consecutively
- these were all LNWR additions, not RCH codes (at least, not until much later)

Note also that the RCH code included Express Goods Class A (3-2) and Class B (1-4). In the LNWR implementation these were Special Express Goods (where authorised) and ordinary Express Goods, respectively.

Does that answer your question?

Reg,

Thanks for your reply.

With respect to Engine Head Lamps and Boards 1 to 9 inclusive, I wanted to match the correct bell code to each one with respect to the 1909 document, but 1905 or 1911 will do just as well. I'm confident I have matched each one except no.3 and no.7 Engine Head Lamps.

With respect to No.3 Lights - Fish, Meat, Fruit, Horse, Cattle, or Perishable train composed of Coaching Stock for lets say 1905 and 1911, I wanted confirmation that the bell code would be consecutive 5 beats and not 1-1-1-3 given on the society website. Likewise No.7 Lights, does 2-3 cover all descriptions?

Regards, Gareth

Yes Gareth, I see what you mean!

Firstly, I have to point out that the list "Bell Codes" on the website does not represent the codes used in LNWR boxes pre 1923 - it includes codes only invented and used later in the LMS period, for example the following ones, including some inherited from the L&YR:
3-1-1
2-2-1-1
1-1-3 (from 1.1925) -- I think 1-1-1-3 is a typo!!
2-2-3 (from 7.1928)
1-3-1 (from 9.1929?)
all OGLO codes (4-1-1, 4-2-5, 4-1-5)
2-1-4
1-5-2
1-2-1
3-3-5
etc etc ...
also, the descriptions for 5, 3-2, 1-4 and 4-1 are different from those used in the LNWR period, having been changed in Jan 1925, July 1928 and again in Jan 1933.

I can only assume that someone must have copied them from the LMS 1947 Block Regs book, and assumed that the bell codes never changed (despite there being many more categories of vacuum fitted freight train in 1947 than in 1916, for example!)

* Webmaster please note! Would you like a copy of the LNWR codes (say 1916 issue) to replace the one on the website?

So, to answer your question, in the LNWR Regulations (1905/11/16 and presumably 1909 also)
"Fish, Meat, Fruit, Horse, Cattle, or Perishable train composed of Coaching Stock" was 5 beats. (same as No.3 lights)
"Light Engine, Light Engines coupled together, or Engine & Break" was 2-3 (same as No.7 lights)
[ie included what was later signalled as 1-3-1]

Many of the codes changed again in 1950 for BR standardisation, but I won't confuse the issue with that!

Also, while not relevant to your period, it should be remembered that the lamp codes were modified in May 1918. The codes using 3 lamps were changed to reduce the use of oil in the wartime emergency. If you stick to the period 1903 to 1918, then it's all fairly simple!

Simon, I admit I had to search the site to find them! It's actually a link from the Glossary - www.lnwrs.org.uk/Glossary/BellCode.php

I'll either (a) get the page scanned and email it or (b) put a photocopy in the post. Your postal address is in the Newsletter, no doubt.

Glad to be able to help improve the quality of the information.

Thank you. The glossary - a truly impressive piece of work, must have taken a lot of time and patience.

Codes amended using LNWR 1916 Appendix supplied by Richard Foster. As they are in the glossary have just put in Bell Signals not the notes etc. Fun enough typing them in, theres no plot to follow.

Thanks for pointing it out Reg, you are most welcome to check it !

Jolly good Simon, another minor improvement to the Webbsite!

I am pleased to say that your typing is 100% accurate. However, please note:

You have included the * against four of the signals. This denotes the codes which were NOT preceded by "call attention" (one of them was only used as a reply to another signal, and another as an addendum). I suggest you should either include the explanation, or delete the * entirely??

Similarly, against 3-2 and 1-4 it says "SEE NOTE BELOW". You should include the note, as these two signals were used rather differently on the LNWR to other railways. Without the note, this is not apparent.

Finally, note that, as shown at the head of the page, L&NW additions in distinctive type, thus:- ("TAKE OFF SLOT, TRAIN WAITING"). Again, I think it is important to include this, as it illustrates the LNWR thinking as distinct from the RCH Standard. Most of these LNWR variations were in place before 1905, but note that the following were added subsequently:
c1909 - "I L C for Rail Motor Car or Motor Train?" 3 - 1 - 2
3/1914 - "I L C for Stock Train required to run at E P Train speed?" 3 - 1 - 1
c1915 new category "Goods Trains fitted with vacuum break throughout" included (with NPCCS) in code of 5 consecutively
(previously, c1905-15, they had been described and signalled as "Perishable", also covered by 5 consecutively)

Hope you agree!
