4 Wheel Drive/SUVs/Railway signals control system.



In cases where specific railway signals are not working on the railway tracks, is it possible for the motorman or train driver getting automatic alarms inside the train ?.

Can a electronic panel and a signal control system be designed within the train cabin to the motorman indicating railway signals strategic locations and signal status (red,green,orange etc) displayed as a map at a distance say 1 or 1/2 km before the train approaches a railway signal ?.

Can i get inputs, views and opinion from your end regarding the pros and cons if such a system is integrated within the train cabin to the motorman ?.

Examples :

The railways signals positioned at strategic locations near the railway tracks can be completely or partially eliminated if such a system is built ?

The motorman will have a better control of train operations ?.

The cost of building and implementing these systems will be not a significant amount ?.

These systems if implemented will better for Long distance trains as compared to short distance Local trains transport or vice versa ?.

Awaiting your reply,

Thanks & Regards,

ANSWER: Prashant,

The type of system you are interested in should be easy, and fairly inexpensive to install.  They could operate off of a motion sensor, metal detector loops,  cameras, to name a few.  A computerized camera system would be able to send a picture to the train from each intersection, or station, and could be viewed on a monitor, or even a computer.
I think that you would, still want a barrier of some sort, such as a gate tied in with the system, just to make sure that the motorists know that a train is in the area.

I think that this is a great idea, and one that would promote safety greatly.

I would say that there still needs to be some type of warning system at the specific intersection, to notify the drivers that there is a train on the tracks, and in the vicinity.  The reason I say this, is that the train cannot be slowed down quickly enough to evade a motorist that may pull in front of the train.  The train notification would be a safety device to confirm that the train engineer/operator of a pending situation, such as a stalled vehicle or animal on the tracks.  With enough advance warning, the engineer could start an emergency slow down or stop before the blocked area or track.  The safety system, could, also notify the engineer of a failure of a safety system at an intersection.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you.

I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles, and I suggest that you obtain a repair manual for mechanical problems and do some research before asking your question. Most mechanical questions can't be answered completely without looking at, or listening to the vehicle in person.


40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
