Lua Kazordoon Wagons - small problem

[Galaxy]

Hey, I found a script on otland. BUT I have no idea how to add more wagons to that script ;( There is just a space for 1 wagon. ;(

Here is the script...

local positions = {
				--[[ Here is how it goes if player clicked the wagon which is on pos1 then he goes to that on pos2 and vice-versa]]--
					[1] = { pos1 = {x=94,y=114,z=7}, pos2 = {x=91,y=123,z=7} },   
					[2] = { pos1 = {x=94,y=119,z=7}, pos2 = {x=83,y=123,z=7} }
}
local days = 1182930 --empty storage, must be the same as the one in the npc file
 
function isWalkable(pos)
	if getTileThingByPos({x = pos.x, y = pos.y, z = pos.z, stackpos = 0}).itemid == 0 then return false end
	for i = 0, 255 do
		pos.stackpos = i
		local tile = getTileThingByPos(pos)
		if tile.itemid ~= 0 and not isCreature(tile.uid) then
			if hasProperty(tile.uid, 2) or hasProperty(tile.uid, 7) then
				return false
			end
		end
	end
	return true
end
function doTeleportToClosestFree(cid,pos, x, y)
	local places = getArea(pos, 1, 1)
	for i = 1,#places do
		if isWalkable(places[i],false,true) then return doTeleportThing(cid,places[i]) and doSendMagicEffect(places[i],10) and true end
	end
	return false
end
function onUse(cid, item, fromPosition, itemEx, toPosition)
	local Teleport_to,p = false,toPosition
	if getPlayerStorageValue(cid,days) < os.time() then return doPlayerSendCancel(cid,getPlayerStorageValue(cid,days) > 0 and "Your subscription have ended." or "You havn't subscribed yet.") and doSendMagicEffect(p,2) end
	for k,v in pairs(positions) do
		if doComparePositions(p, v.pos1) or doComparePositions(p, v.pos2) then Teleport_to = doComparePositions(p, v.pos1) and v.pos2 or v.pos1 break end
	end
	if not Teleport_to then return doPlayerSendCancel(cid,"wagon is out of service.") and doSendMagicEffect(p,2) end	
	if not doTeleportToClosestFree(cid,Teleport_to, 1, 1) then return doPlayerSendCancel(cid,"You need to inform wagon master about this rail block.") and doSendMagicEffect(p,2) end
	return true
end

Thanks for support
