Haan bhai I have personally experienced these things , ALD MGS section ka Jo congestion se haal hai , koi ni predict kr sakta arr time @ ALD..
Bt phir bhi RAJDHANI , GR , DURONTO tak thik hai , bt 130 MPS waali train bhi agar bahut late ho aur uske aagey koi on time train ho toh MPS train OT the on time train and this continues and delays the on time train..
Ab har train toh 130 MPS ni ho sakti na ..
