Just as I hoped when I first saw the report, local railway historian and expert Ian Pell has been in touch to add his comments to the matter of the 1873 railway accident I featured the findings of last weekend.
I was surprised at the time that signalling systems and control procedures were already so complex, even though the railway was still effectively in it’s infancy; now Ian lights the whole thing up. It’s truly fascinating.
If you’d like to meet Ian, he has a talk coming up soon in Brownhills – he’ll be giving a talk entitled ‘From Water to Oil’ on Tuesday, 23rd October 2018 at the Scout Hut, Barnetts Lane, Brownhills for the ‘Back the Track’ Group. 18.45 for 19.00 start.
If you have anything to add, please do – comment here is welcome, as is buttonholing me on social media or a good old fashioned email to Brownhillsbob at Googlemail dot com. Thanks.
A Question if Visibility
Such incidents were not uncommon on the railways of the 1870s. At that time the wagons or carriage were unfitted, ie:- there was no continuous braking system throughout the train, and as such the trains relied on the locomotives brake, the guard’s van’s brake and the skill of the crew in understanding the gradients of the line. The event was not really due to the system being overloaded but more the signalling system’s limitations. A similar rear end collision occurred on 4th March 1873 on the Cannock line from Birchills to Bloxwich, where a proceeding goods train slipping on the up hill gradient was rear ended by a passenger train injuring 12 passengers. Train travel in those days was a lot more exciting!

Put simply –
Permissive block signalling. Under the permissive block system, trains were permitted to pass signals indicating the line ahead was occupied, but only at such a speed that they could stop safely driving by sight. Permissive block working could also be used in an emergency.
Absolute block signalling is designed to ensure safe operation by allowing only one train to occupy a defined section of track (block) at any time. A train approaching a section is offered by a signalman to his counterpart at the next signal box. If the section is clear, the latter accepts the train, and the first signalman may clear his signals to give permission for the train to enter the section. This communication traditionally takes place by bell codes and status indications transmitted over a simple wire circuit between signalmen using a device called a block instrument, although some contemporary block working is operated wirelessly. This process is repeated for every block section a train passes through.
Below is a copy of the 1899 signalling diagram for Brownhills, when the original signal box was replaced with the new box that was to remain until its closure in January 1967. Far left is the distant signal in question. It also shows the down goods loop, adjacent to the goods shed which existed in this form for a number of years. It was approved for construction on 17thOctober 1873.
I think the signal andkindred is referring to is the Norton Junction distant adjacent to the pony centre off the Pelsall Road – although I could well be wrong. The distant signal in the report was closer to Brownhills between bridge Nos. 68 Bullows Road and 69 Clayhanger Lane.
Hope these ramblings are of some assistance.
PS. For anyone who’s interested I’m due to give a presentation entitled “From Water to Oil” on Tuesday, 23rd October at the 2nd Brownhills Scout HQ, Barnetts Lane, Brownhills for the “Back the Track” Group. 18.45 for 19.00 start.
