A small improvement,

You could do:

pawn Code:

IsVehicleRcTram( vehicleid )
{
  new model = GetVehicleModel(vehicleid),
    bool:result;

  switch(model)
  {
    case 441,449,464,465,501,564 : result = true;
    default : result = false;
  }
  
  return result;
}

I don't know if it's faster or what else, but it looks better...only my advice :P
