Weird behaviour when passing array to method in C

I wrote a method that takes as parameters two stations and an array of railway trails.

typedef enum { MA1, MA2, MA3, MA4, MA5, MA6, MA7, 
    MA8, MA9, MA10, MA11, MA12, MA13, MA14, MA15, MA16} RailwayTrack;

typedef enum { S1, S2, S3, S4, S5, S6} RailwayStation;

typedef struct TrainData {
    int currentProgress;
    RailwayStation startStation;
    RailwayStation endStation;
    int railwayPathLength;
    RailwayTrack *railwayPath;
} TrainData;

#define MAP1_TRAIN_N1 getTrainData(S1, (RailwayTrack[]){ MA1, MA2, MA3, MA8 }, S6)

TrainData getTrainData(RailwayStation startStation, RailwayTrack railwayPath[] /*ERROR HERE?*/, RailwayStation endStation) { 
  TrainData trainData;
  trainData.startStation = startStation;
  for (int i = 0; i < sizeof(railwayPath)/sizeof(RailwayTrack); i++)
  {
    printf("Eli: %d\n",railwayPath[i]);
  }
  //OUTPUT: Eli0, Eli1

  RailwayTrack test[] = { MA1, MA2, MA3, MA8 }; //TEST ARRAY CAUSE ABOVE IS NOT WORKING
  for (int i = 0; i < sizeof(test)/sizeof(RailwayTrack); i++)
  {
    printf("Eli: %d\n",test[i]);
  }
  //OUTPUT: Eli0, Eli1, Eli2, Eli3
  
  trainData.railwayPath = railwayPath;
  trainData.endStation = endStation;
  return trainData;
}

The problem is that the array given as parameter won't get print out completely but just until the first 2 elements. You can see that as parameter I am passing an array of 4 elements but in the Logs only the first 2 are visible.

I was finally able to understand thanks to some help that I needed to pass the size of the array as parameter too. Thanks everyone for the help.

sizeof(railwayPath) is giving you the size of pointer not array in C. You do not pass the array, only reference (pointer to it).

You need to pass size as a parameter:

TrainData getTrainData(RailwayStation startStation, RailwayTrack railwayPath[],
                       size_t railwayPathSize, RailwayStation endStation) {
