I assumed for the example that it was straight track to keep it consistent with your question to me.But a curve and speed restriction present an interest question. The travel is still basically on a vector -the track. The train will not depart from the track most of the time (we hope!) The train would have to know when it is entering the restricted speed zone. This might be a problem because of the increase in maximum position error (15 feet per second). So if the curve close enough to the departure station so that GPS' error is not ecessive, you don't nee wayside equipoment there. Further away from a threshold we agree upon, you'd need wayside equipment. |
