func_tracktrain - 3 problem

[Koji6ac9H]

Hello everyone.
I'm doing more traitor-button for your TTT server, the map I made cs_assault button which when pressed leaves the train, but there are three problems:
1 - The train moves jerkily
2 - Train does not damage
3 - If you stand in front of the train, it will get stuck and the server will down.

The map ttt_67thways_v3 have cars built on the same principle this,but if you stand in front of them they will get stuck, but the server does not fall.
Plz tell me what could be the problem

Code:

aprop={}
table.insert(aprop,{Map="cs_assault",Class="prop_physics",Model="models/hunter/plates/plate2x2.mdl",Pos=Vector(6812,7185,-464),Ang=Angle(90,180,180),Color=Color(255,255,255,0),Motion=false,NoDraw=true})
table.insert(aprop,{Map="cs_assault",Class="path_track",Pos=Vector(7232,8756,-500),Keys={targetname="tend",orientationtype=1}})
table.insert(aprop,{Map="cs_assault",Class="path_track",Pos=Vector(7232,3000,-500),Keys={targetname="tstart",orientationtype=1,target="tend"}})
table.insert(aprop,{Map="cs_assault",Class="func_tracktrain",Pos=Vector(7232,3456,-490),Keys={targetname="train",target="tstart",health=200,height=4,MoveSoundMaxPitch=200,MoveSoundMinPitch=60,wheels=50,volume=10,renderamt=255,rendercolor="255 255 255",startspeed=1600,spawnflags=512}})
table.insert(aprop,{Map="cs_assault",Class="prop_dynamic",Model="models/props_trainstation/train001.mdl",Pos=Vector(7232,3456,-480),Ang=Angle(0,-90,0),Color=Color(255,255,255,0),Keys={targetname="tprop",solid=6,MaxAnimTime=10,MinAnimTime=5},Motion=true,Parent="train"})
table.insert(aprop,{Map="cs_assault",Class="ttt_traitor_button",Pos=Vector(7129,5583,-474),Keys={description="Вызвать поезд",wait=-1,OnPressed="train,StartForward,,1,-1"}})

function propSpawn(class,model,pos,ang,color,motion,draw,key,parent)
	local ent = ents.Create(class)
	if !IsValid(ent) then return end
	if model!= nil then ent:SetModel(model) end
	ent:SetPos(pos)
	if ang!= nil then ent:SetAngles(ang) end
	if key!=nil then
		for i,j in pairs (key) do
			ent:SetKeyValue(i,j)
		end
	end
	ent:Spawn()
	ent:Activate()
	local phys = ent:GetPhysicsObject()
	if IsValid(phys) then
		phys:EnableMotion( motion )
		phys:Wake()
	end
	if color!= nil then ent:SetColor(color) end
	if draw!= nil then ent:SetNoDraw(draw) end
	if parent!=nil then ent:SetParent(ents.FindByName( parent )[1]) end
end

function InitPostEntity()
	for k,v in pairs (aprop) do
		if v.Map == game.GetMap() then
			propSpawn(v.Class,v.Model,v.Pos,v.Ang,v.Color,v.Motion,v.NoDraw,v.Keys,v.Parent)
		end
	end
end
hook.Add("InitPostEntity","asdads",InitPostEntity)

P.S. Sorry for my English

You should just modify the map and make the tracktrain yourself. It doesn't seem ideal to do it with lua, but that's my opinion.
