Node Based Train Kit 2

Hello, I am trying to achieve a smooth moving train kit based on nodes. This already works as of itself but lags a lot on server side as it counts each carriage as an individual train. Trains are counted by 2 nodes each.

I tried modifying the script and multiple other solutions to make this work, but it still lags as much server side.

local rs = game:GetService("RunService")

local train = script.Parent

local curSpeed = train.CurrentSpeed

local nodes = train.Parent.Parent.Nodes
local nodeReady = nodes.Parent.NodeReady

local loco = train.Locomotive
local front = loco.Front
local back = loco.Back
local base = loco.Base
local gap = (front.Position - back.Position).Magnitude
local loco_model = loco.Model

local startingNode = train.StartingNode

print("started2")
wait(10)
repeat wait() until nodeReady.Value 

function SetStartingNode()
	front.Current.Value = nodes:FindFirstChild("Node_" .. startingNode.Value)
	back.Current.Value = nodes:FindFirstChild("Node_" .. startingNode.Value)
end

function NextNode(target)
	local curNode = target.Current
	local nextNode = curNode.Value.NextNode.Value
	
	curNode.Value = nextNode
end

function Move(target, deltaTime)
	local curNode = target.Current.Value
	local nextNode = target.Current.Value.NextNode.Value
	
	if not nextNode then
		curSpeed.Value = 0
		return
	end
	
	local distanceTraveledOnSection = (curNode.Position - target.Position).Magnitude
	local sectionLength = (curNode.Position - nextNode.Position).Magnitude
	local newAlpha = ((distanceTraveledOnSection + curSpeed.Value * deltaTime)) / sectionLength
	
	target.CFrame = curNode.CFrame:Lerp(nextNode.CFrame, newAlpha)
	
	if newAlpha >= 1 then
		NextNode(target)
	end
end

rs.Heartbeat:Connect(function(deltaTime)
	Move(front, deltaTime)
	Move(back, deltaTime)
	
	base.CFrame = CFrame.new(back.Position, front.Position) * CFrame.new(0,front.Size.Y/2 + base.Size.Y/2,-gap/2)
	loco_model:SetPrimaryPartCFrame(base.CFrame * CFrame.new(0,base.Size.Y/2 + loco_model.PrimaryPart.Size.Y/2,0))
end) 


SetStartingNode()

I have looked into the Devforum multiple times but have still not found the solution. Please keep me updated.
