We will be offering 08-hauled shunter trips at Llangollen during the diesel weekend 29-30th September.

Rail passengers in the UK are not restrained at all and there are no systems to mitigate the effect on passangers of high levels of deceleration (eg airbags) so it might actually result in more harm by decelerating more severely. Railway vehicles have pretty good crashworthiness these days and...

The Vac reservoir on a DMU, AIUI, is to allow the brakes to be released quickly when pulling away from a standing start. This is because the exhauster is mechanically driven from the engines so will not be running at full speed when the unit is at a stand.

To further expand on the comments above, Wikipedia is your friend. https://en.wikipedia.org/wiki/Cutoff_%28steam_engine%29 The best source I've found for understanding steam loco operation is the BR Enginemans handbook ('black book') last published in the 1950's. It can be got for around a...

The 1950 BR rule book forbids propelling trains except under specific circumstances, one being to use an autocoach, so the driver would actually be at the front of the train and in control of the brakes and regulator. https://en.wikipedia.org/wiki/GWR_Autocoach

I've been told they had to be in between the loco and the coaches so the driver would get fire alarm indications etc.

I can only speak from experience on preserved locos. Before starting there's between 5 and 15 minutes of preparation and brief exam for obvious defects, after getting the engine running it will take a few minutes to get the air system up to working pressure. Once there you can start brake tests...

There is a section called 'Exclusion from Mainline Railway Requirements' on the ORR site: http://orr.gov.uk/what-and-how-we-regulate/health-and-safety/regulation-and-certification/rogs/exclusions-from-mainline-railway-requirements If you check the general notes about ROGS and what European...

Sources close to NR have told me the planning work has already started and the Welsh Assembly are funding it to give North Wales better access to Liverpool Airport.

As I understand it when in service many locos didn't get much chance to cool down in between duties and as correctly stated above the nice warm interior tended to keep the moisture levels down. Modernisation era locos are not particularly watertight, and those stored outside, perhaps only being...

Absolutely. There is no business case for any Heritage Railway in the UK to do this. Heritage railways generate revenue from operating steam services, which this would not enhance, and why would anyone put up a load of OHLE and spoil everyones pics?

Just to muddy the water further on diesel electric locos (not sure about AC electrics) the cabs would be designated 1 and 2 and often the sides of the vehicle would be referred to as A and B, due to the larger diesel power units having A and B cylinder banks. For example when describing a...

On the older diesel electrics it's a combination of engine revs and generator/alternator excitation. For example on a 37 as you open the power handle the engine revs will stay pretty much constant but the load regulator will be increasing the field. As you demand more power the field and engine...

Diagrams for Llangollen Diesel Day 21st September now confirmed: http://www.llangollen-diesels.org.uk/?p=2138

Not sure about the SVR but at Llangollen on a diesel experience you get to drive one round trip with a train on the back. On the steam experience you share with another punter - you each get to drive one way, and fire the other.

Correct the loco was weathered at Llangollen.

Hi, see my reply PM, which should help. The voltage from the auxiliary generator was indeed regulated by an electromechanical carbon pile AVR, though this was replaced with an electronic one in the refurb locos. Many preserved 37s have also had this upgrade..

There are plenty of scanned documents floating about, PM me and I'll see if I can help you.

No idea on the price of the original contract, that's an interesting question and I'd be interested to know myself. As to current price - say 30-40k scrap price, depends on the current per ton proce of the metals but copper is pretty high at the moment and there's plenty of copper in a diesel...
