i'm trying to put in my server roller coaster system.
but i want everytime when the roller finish his path he will be removed.

local storage = 242526
local interval = 10

function tileChecker(pos)
    local myTable = {}
    if (type(pos) == 'table') then
        for i = 1, 5 do
            pos.stackpos = i
            local thisID = getThingFromPos(pos).itemid
            if thisID > 1 then
                table.insert(myTable, thisID)
            end
        end
    end
    return #myTable > 0 and myTable or nil
end

local function findItem(pos, t)
    if (type(pos) == 'table' and type(t) == 'table') then
        for _i, i in ipairs(tileChecker(pos)) do
            if isInArray(t, i) then
                pos.stackpos = _i
                ret = getThingFromPos(pos).uid
                break
            end
        end
    end
    return ret
end

local function moveTrain(p)
	doCreateItem(p.t, 1, p.new)
    doTeleportThing(p.cid, p.new, FALSE)
    doRemoveItem(findItem(p.pos, {7131, 7132}))
	
end    

function onStepIn(cid, item, pos)
    local Rail = false
    local Rails =
