This is safety equipment that must be aboard all trains on the Serpentine and Tuna Tunnel Terminal subdivisions of the TRYA (Terminal RailwaY Association - jointly owned by the railways that service Nu'u-Sara, and its name and logo is inspired by a similar entity in Saint Louis)

From the TRYA (Terminal RailwaY Association) Safety Manual....

"Safety equipment for the Serpentine Tunnels and Tuna Terminal Tunnels.

The Serpentine Tubes, forming the bulk of the Serpentine Subdivision, is OPO (One Person Operation) territory. The same is required in the Tuna Terminal Tunnels on the Tuna Terminal Subdivision. Train engineers driving on these sections must be familiar with emergency protocols for the tunnel, and must know how to use the Tunnel Telephone lines in case of radio failure or distortion, it should also be noted that the line between Polynesia Terrace and the South Grotto has some "dead zones" where the radio either doesn't work, or there is heavy interference, the Tuna Tunnels have ever more such areas. Note that the standards for the Tunnel Telephone lines are based on Aga O Sara (AOS), in turn based on those of Network Rail and London Underground in the UK, but is considered a Matriarch's Railway Authority (MRA) compliant form of communications.

Only 4-rail equipped trains may use the entire tubes, but pantograph-equipped rolling stock may go into the tunnel as far as the turnback center siding at North Grotto, past Clifford Street.

At the same time as doing a brake test at the start of a journey involving the Serpentine Tubes, one should take care to ensure that the needed equipment is present.

Firstly, the communications console must have a pair of "Alligator Adaptor" clips, labelled top and bottom, for connecting to the Tunnel Telephone wires. If stopped in a tunnel, remember to clip the top to the top wire, and the bottom to the bottom wire. When connected, switch the communicator setting to "Tunnel Telephone", "Telefoni Aga" or "TTL/TA", depending on the model. A portable Tunnel Telephone communicator is also allowed. Use the "Tone/Current" button, held down for five seconds, if the current needs to be cut manually.

*If there is a known problem with the Tunnel Telephone wires in a tunnel, the station preceding it will have the "No Telephone" pictogram next to the signals by the tunnel. In this case, a radio test must be done.

**Besides the wires, the adaptor or a portable headset may also use dedicated sockets, found in some locations inside the tunnel, as well as at each tunnel headwall. For this purpose, the "Control" socket is to be used, not "Auxillary" nor "Public Address."

Secondly, each cab must have, at minimum, one or more Class U ("Universal") fire extinguishers. These are generally designed to be used in one go, due to the way the contents are pressurized, so doing a partial spray to "test" is NOT allowed, as it drops the effectiveness very much.

Thirdly, every engineer driving in this section must have AOS certified anti-shock boots, in his or her size. These are the same kind of boots worn with ELVIS (ELectrical VISibility) suits of rail workers in 4-rail territory.

Fourthly, similarly, a sealed bag with a pair of electrical gloved certified for up to 1,500 volts (in case of a spike) must always be kept. If the bag isn't sealed, the gloves need to be replaced.

Fifthly, it is imperative to have a short circuit bar, often nicknamed a "Johnny 5" (the robot from the movie "Short Circuit"), or a "Wooden Crowbar" to cut track power if needed. Regardless as to how the tracks were powered off, a Johnny 5 MUST be placed across the track in case of accidental re-energizing attempt. The "crowbar" shaped part must be atop the positive rail, with the metal plate touching. The second plate MUST be touching the negative rail. For cutting the power in an emergency (for evacuation), there is a hierarchy of preferred methods. Firstly, contact the dispatcher via radio, or if needed, via Tunnel Telephone. If that is not possible, open the right-hand window and rub the wires together. If need be, open the left-hand window instead, and also rub the wires, if they are not available on the other side. Using a short circuit bar is the LAST RESORT. If doing this, make sure to LOOK AWAY AND COVER YOUR EYES, as the resulting arcing, while brief, can cause temporary or permanent vision damage. Regardless as to which protocol was followed, it should ideally be placed as close to the front or back of the train as possible, especially if the train is to be evacuated. Each station has spare short circuiting bars, as do the alcoves in the areas where track sections change in the tunnel. In such an area, if possible, a Wooden Crowbar must be placed at both the front and back of the train, unless fire or another hazard makes this not feasible.

Sixthly, a "mini-ladder" must be on hand, in case evacuation onto the tracks needs to happen. Ensure that it is secure, and that the Short Circuit bar is beneath it. Each cab must have a mini-ladder in case of evacuation this way.

Finally, each cab for a passenger train must have a minimum of two "Disco Ball" type signals. In the event of having to stay in the tunnel for a long time, whether or not evacuation is needed. One should be placed atop the short circuit bar, there is an indentation for this. The other one is to be used in the event that the train is stopped just past a curve, place the ball on a wall fixture at the start of the curve.

In the event of evacuation, all passengers must be led either to the nearest station, or the nearest other escape. As most stations are shared with the AOS, at these stations AOS staff will take the lead in any evacuation."

The equipment is mostly inspired by actual stuff that exists.

I thought WillM3luvTrains may especially find this interesting

Wow you said a mouthful! Then again I just woke up, but I saw you mentioned me and so I decided to take a look. Some of this I had to reread.

This is interesting to say the least. And it's great, not to mention essential to have all the safety equipment needed including the fire extinguisher, every place needs one of those things!

The telephone with alligator jacks (if that's not what they're called please let me know, but they do remind me of jumper cables used to help jump-start cars) seem interesting and I think I kind of get how to connect them, I have a mental picture of what you might be saying, or what you're saying.

Very creative stuff, stuff I didn't think of when creating my fictional railroads and should have thought of! Shows how smart and attentive I really am!

I'd critique but I don't have the mentality or feel-like to do so.

Thanks for sharing.

Thank you.

The fire extinguisher is important, every train should have at least one, preferably one per cab and also one per passenger car.

The inspiration for those was based on what's actually used on a specific line, the Great Northern City line owned by Network Rail in London, and USED to be used in the London Underground (but they abolished the use of Tunnel Telephones recently) Alligator clip and crocodile clip are both valid, and one of the most common uses for that kind of connection is for jumper cables for jump-starting cars, the clips are also known as automotive clips or battery clamps in this context. Also, these alligator clips are specially shaped, because besides being able to open up and attach to the phone lines, they can also be plugged into a special socket. Again, based on actual practice. Regrettably the video I first saw those on is on Youtube, HOWEVER, you can see a handset here... www.ltmuseumshop.co.uk/christm… (this version used a different kind of connector, but I've seen one with alligator clips) Also, an explanation is here... www.yumpu.com/en/document/read… In the case of the railways of Nu'u-Sara, there are both portable tunnel telephones, like is shown, and many train communication consoles will have adaptor cables, and a dial or switch to change between different modes (typically radio, tunnel telephone, and general announcement, the last being important for One-Person-Operation in passenger trains) There are also portable units that double as walkie-talkies and tunnel telephones.

Well, we all think of different stuff. I'm on a discussion board, that has a thread where people discuss fictional transit systems, some people go into different kinds of detail about all kinds of things...maintenance schedules, rolling stock/fleet numbers, everything. I even came up with local slang and terminology for some things railroad related. Such as "Slacks, Sarongs, Saris, and Suits".....which refer to the different types of employees for the railroads.

Another thing, one of the trains that uses this equipment is in a picture I put up, the "train, cats and a girl"
